Mataram, Indonesia – Indonesian authorities have apprehended Ais Setiawati, a key figure in a major narcotics network led by Ko Erwin, in a coordinated operation with the National Police’s Criminal Investigation Unit (Bareskrim). The arrest, which took place on Thursday, February 26, 2026, in Mataram, West Nusa Tenggara (NTB), comes as part of a broader crackdown on the illicit drug trade within the region. This development marks a significant step in dismantling a sophisticated operation that allegedly involved corrupt law enforcement officials and facilitated the movement of narcotics across multiple Indonesian provinces.
Ko Erwin, a notorious drug kingpin, was simultaneously arrested in Tanjung Balau, North Sumatra, near the Malaysian border, according to officials. The coordinated nature of these arrests underscores the intensified efforts to combat drug trafficking and hold those involved accountable. Ais Setiawati’s role as the treasurer for Ko Erwin’s organization highlights the financial complexities inherent in large-scale drug operations, and the subsequent investigation is expected to focus heavily on tracing the flow of funds and identifying other key players involved in the network.
The arrests follow a period of investigation that revealed connections between Ko Erwin and several individuals within the police force, including former Head of the Bima City Police Narcotics Unit, AKP Malaungi. This alleged collusion raises serious concerns about corruption within law enforcement and the potential for compromised investigations. The ongoing inquiry aims to determine the extent of this corruption and ensure that all those complicit are brought to justice. The case underscores the challenges faced by Indonesian authorities in tackling deeply entrenched criminal networks that exploit vulnerabilities within the system.
Unraveling the Network: Ais Setiawati’s Role and Connections
Ais Setiawati, identified as a crucial financial conduit for Ko Erwin’s drug trafficking operation, was responsible for managing the proceeds from the sale of narcotics sourced from an individual named Anita, who is reportedly the wife of a police officer, Bripka Irfan. According to Kombes Roman Elhaj, Director of Narcotics at the NTB Police, Ais’s capture represents a significant breakthrough in the investigation. “Ais was responsible for managing the funds generated from the sale of narcotics,” Elhaj stated during a press conference at the National Police Headquarters in Jakarta on Friday, February 27, 2026. IDN Times reported on the arrest, detailing her key role within the organization.
The investigation has also revealed that Ais Setiawati had a meeting with AKP Malaungi at the Hotel Marina Inn in Bima. This meeting, attended by Ko Erwin and Anita, is now under scrutiny as investigators attempt to determine the nature of their interaction and whether it involved any illicit agreements or financial transactions. The involvement of a former high-ranking police official in a drug trafficking network is a particularly troubling development, raising questions about oversight and accountability within the Indonesian National Police.
Following her arrest in Mataram, Ais Setiawati was transported to Jakarta for further questioning by the Directorate of Narcotics Criminal Investigation at Bareskrim Polri. Authorities are focusing on uncovering the full extent of the financial network and identifying any additional assets linked to Ko Erwin and his associates. The investigation is expected to be complex, given the efforts to conceal funds and the potential involvement of multiple shell companies or intermediaries.
Coordinated Raids and the Pursuit of Justice
The simultaneous arrests of Ko Erwin and Ais Setiawati were the culmination of a coordinated operation between the NTB Police and Bareskrim Polri. Ko Erwin was apprehended near the Malaysian border in North Sumatra, indicating an attempt to flee the country and evade capture. Detik News reported that Erwin was captured although attempting to escape to Malaysia. This suggests a well-planned operation to intercept him before he could cross international borders.
In addition to Ais Setiawati, a total of six suspects linked to the narcotics network were transported to Jakarta for interrogation. These individuals, identified as YI, HR, AN, IR, Malaungi, and Ais, will be subjected to a confrontational examination alongside Ko Erwin to clarify their respective roles and connections within the organization. Brigjen Eko Hadi Santoso, Director of Narcotics at Bareskrim Polri, emphasized the importance of this confrontational approach, stating that This proves crucial to reconcile conflicting testimonies and establish a clear understanding of the facts. “We require to confront each other’s testimonies to find out the truth,” Santoso explained.
The investigation is not only focused on identifying the individuals directly involved in the drug trafficking operation but also on tracing the flow of money and uncovering any potential corruption within law enforcement agencies. Authorities are examining financial records and conducting interviews to determine the extent to which Ko Erwin may have bribed or influenced officials to facilitate his illicit activities. The pursuit of justice extends beyond simply arresting the perpetrators; it also involves addressing the systemic issues that allowed such a network to flourish.
Challenges in Tracing Funds and Uncovering Corruption
One of the primary challenges facing investigators is the difficulty in tracing the financial transactions associated with the drug trafficking operation. Ais Setiawati reportedly claimed to have no bank accounts or financial records, suggesting that she may have been instructed to dispose of any evidence that could link her to the illicit funds. “She said she didn’t have any accounts, ‘I don’t have a passbook, sir,’” Elhaj recounted. This tactic is common among individuals involved in criminal activities, as it makes it more difficult for authorities to track the movement of money and identify the ultimate beneficiaries.
The investigation is also complicated by the alleged involvement of AKP Malaungi, the former Head of the Bima City Police Narcotics Unit. His position within law enforcement would have provided him with access to sensitive information and the ability to obstruct investigations. The extent of his involvement and the nature of his relationship with Ko Erwin are key areas of focus for investigators. The case highlights the vulnerability of law enforcement agencies to corruption and the need for robust internal controls to prevent such abuses of power.
Authorities are committed to conducting a thorough and impartial investigation to uncover the truth and hold all those responsible accountable. The Directorate of Narcotics Criminal Investigation at Bareskrim Polri is working diligently to analyze financial records, interview witnesses, and gather evidence that will support the prosecution of the suspects. A press conference is scheduled for next week to provide a more detailed update on the progress of the investigation.
Looking Ahead: Next Steps and Potential Outcomes
The arrests of Ko Erwin and Ais Setiawati represent a significant victory for Indonesian law enforcement in its ongoing efforts to combat drug trafficking. However, the investigation is far from over. Authorities are expected to continue pursuing other members of the network, tracing the flow of funds, and addressing the underlying issues of corruption that enabled the operation to thrive. The upcoming press conference, scheduled for next week, is anticipated to provide further details on the investigation’s progress and potential future actions.
The case also raises broader questions about the effectiveness of Indonesia’s drug enforcement policies and the need for a more comprehensive approach to tackling the problem. This includes addressing the root causes of drug addiction, providing rehabilitation services for addicts, and strengthening international cooperation to disrupt the supply of illicit drugs. The successful prosecution of Ko Erwin and his associates will send a strong message to other drug traffickers and demonstrate Indonesia’s commitment to combating this serious crime.
The focus now shifts to the legal proceedings and the potential penalties that Ko Erwin, Ais Setiawati, and their co-conspirators may face. Under Indonesian law, individuals convicted of drug trafficking offenses can face lengthy prison sentences, including the death penalty in certain cases. The outcome of the trial will likely have a significant impact on the future of drug enforcement in Indonesia and serve as a deterrent to others involved in the illicit drug trade.
