On Friday evening, April 17, 2026, nearly 100 men were observed running naked through the streets of Trondheim, Norway, prompting a police response and drawing attention from local residents and media outlets. The incident occurred in the Tyholt area of the city, where witnesses reported seeing a large group of nude men moving through residential streets in what appeared to be a coordinated, though informal, gathering.
According to Stian Martinsen Aalberg, operations leader for the Trøndelag police district, authorities received initial reports of approximately 90 naked men running in the vicinity of Kantennelunden on Tyholt. Police patrols were dispatched to the scene to locate and engage with the individuals. In a later update, Aalberg confirmed that officers made contact with a group of 20 to 30 people, stating that the participants were informed that police did not wish to receive similar calls from event organizers in the future.
Local resident Kaja Eriksen, who lives near Kantennelunden, described the scene to Dagbladet, noting that while she found the situation somewhat amusing, she understood why others might consider it inappropriate. She observed that the group had been active since early evening and remained in the area until police intervened. Eriksen similarly noted that there appeared to be additional young people present who were not participating in the nude run but were observing or accompanying the runners.
Police speculated that the event was likely connected to a student gathering, possibly involving individuals from the Norwegian University of Science and Technology (NTNU), while they emphasized that there was no evidence to suggest official NTNU sponsorship or organization of the activity. No arrests were made, and no injuries were reported during the incident.
The occurrence sparked discussions online and in local communities about public behavior, personal freedom, and the boundaries of acceptable conduct in public spaces. While some viewed the act as a harmless, if unusual, expression of spontaneity, others raised concerns about public decency and the potential for such events to disturb residents, particularly in typically quiet neighborhoods like Tyholt.
As of the latest police update on the evening of April 17, 2026, the situation had been resolved, with officers confirming that the group had dispersed and no further action was required. Authorities reminded the public that while freedom of expression is protected, public nudity may still be subject to local ordinances and could result in police intervention if deemed disruptive or non-consensual in nature.
