Multiple reports detail a serious incident at a vocational college in Dortmund where a dispute among approximately ten individuals escalated into violence, including gunfire. Witnesses and police sources confirm that during the altercation, a person used a compressed air weapon, which was initially mistaken for a firearm, and fired shots. The weapon was left at the scene and has been secured by authorities. The suspect fled the scene along with the injured victim, who was involved in the dispute. No injuries from gunfire have been reported, but seven people were lightly injured due to the use of pepper spray by one of the participants. The police are actively searching for two suspects, with one believed to have used a PTB (Physikalisch-Technische Bundesanstalt) certified air pressure gun, which is legally purchasable with proper documentation. The motives behind the fight remain unclear, and it is uncertain whether all involved are students of the college. Authorities emphasize that there was no danger to the public during the incident.
