A violent incident in Barcelona’s Sants-Montjuic district on Sunday morning left four people hospitalized. After stabbing three people inside the shared apartment on Gran Via, a man in critical condition jumped from a fourth-floor balcony.
The attack took place in a flat at number 162, where three men lived together. Mossos d’Esquadra said the suspected attacker entered a bedroom where one roommate was with his girlfriend and began stabbing them. The male roommate was seriously injured, while the woman suffered minor wounds. The noise brought the third resident, who was also stabbed but sustained only light injuries.
Afterward, the man reportedly turned the knife on himself before jumping from the balcony. Emergency services arrived quickly and found him critically injured on the street. One victim remains in serious condition; the other two have less severe wounds, and the attacker is also fighting for his life.
Police have yet to determine what led to the violence. Investigators are working to reconstruct the sequence of events and establish the relationships between those involved. Mossos d’Esquadra say they are considering all possibilities, while forensic teams examine the apartment for evidence. El Periódico reported that authorities had not established a motive and were keeping all options open as the investigation continued.
The incident comes as Barcelona faces renewed attention on residential safety and mental health support, particularly in crowded neighborhoods. The city has seen several emergencies in recent months, including the recent disruption of high-speed rail services, which has put extra pressure on emergency response teams.
While the motive for Sunday’s stabbing remains unclear, the case highlights risks that can arise in ordinary homes. The attacker and the victims lived together, showing how quickly violence can erupt in shared spaces. Until police clarify what happened, the incident remains a reminder of the challenges facing city neighborhoods and the need for better support when warning signs appear. Authorities’ next steps will be watched closely as Barcelona tries to balance public safety with help for people in crisis.
