FOND DU LAC, Wis. (WFRV) - Authorities in Fond du Lac are investigating a fire at a strip mall that broke out early Sunday morning, with evidence suggesting the blaze may have been intentionally set. Firefighters and police officers responded to reports of a fire on the exterior of a strip mall in the 500 block of Peters Avenue around 1:02 a.m. Fond du Lac Police officers were first on the scene and used fire extinguishers to contain the flames until Fond du Lac Fire Rescue arrived to extinguish the fire fully.

No one was inside the building at the time, and no injuries were reported. The fire caused moderate damage to the exterior and minor damage to the interior. Crews had the fire under control within five minutes. Later that morning, police apprehended a 19-year-old Menasha man near the scene who admitted to starting the fire. According to officials, the suspect claimed the act was in response to recent discussions about a potential TikTok ban. “We are relieved that no one was injured, and the office was unoccupied at the time of the fire,” said Chief Aaron Goldstein. “Acts of violence, in any form, are not tolerated, and we remain committed to protecting the safety and well-being of our community. I am thankful for the swift response of our officers in helping knock down the fire and locating the suspect of this arson.” The suspect is being held at the Fond du Lac County Jail, and a charge of arson is being referred to the Fond du Lac County District Attorney’s Office.
