The incident occurred on Sunday morning, around eleven o'clock, when National Police officers responded to an establishment in the Usera district, operating as an 'after-hours' club, after receiving a report of a fight inside.
Upon arrival, police officers found several individuals belonging to two opposing groups. Some of the participants showed injuries, apparently caused by the use of glasses and bottles during the altercation.
The confrontation, which began inside the venue, subsequently spilled out onto the street. Initially, officers arrested eight people, including a minor. Later, the number of arrests rose to twelve.
The detainees are of various nationalities, including Spanish, Bolivian, Peruvian, and Colombian. The investigation remains open to fully clarify the details of the event, although authorities have ruled out any connection to youth gangs.
