The incident happened during the festivities in the Sant Josep neighborhood, when shots were heard. Upon arrival of the Guàrdia Urbana officers, the alleged shooter fled by car at high speed but was eventually apprehended and taken to police facilities.

This event occurs amidst a backdrop of gun violence in the metropolitan area, as this shooting in L'Hospitalet follows another shooting in Barcelona, on Carrer de la Mineria, which resulted in a fatality.
