National Police have detained a 49-year-old man in Leganés as the alleged perpetrator of the homicide of his 53-year-old brother, who was stabbed in their home. The incident occurred on Thursday at 3:00 p.m. following a call reporting a heated argument. This marks the third death by stabbing in the Madrid region during this Christmas period.
In Leganés, a town south of Madrid, a 53-year-old man has died after being stabbed by his 49-year-old brother inside their home. The incident took place on December 25, 2025, around 3:00 p.m., when National Police received a 091 call reporting a heated argument in the residence. Upon arrival, Security Citizen agents found the victim with multiple stab wounds and no vital signs. Medical services confirmed his death at the scene.
The alleged perpetrator, the victim's brother and also Spanish, was arrested on the spot for homicide. Sources from Madrid's Superior Police Headquarters state that both brothers are Spanish nationals. The investigation is led by Homicide Group VI, with support from the DEVI Scientific Police unit.
This event adds to two stabbing deaths that occurred on Christmas Eve in Madrid. The first victim was a 17-year-old Spanish youth stabbed in the left hemithorax on Lagartera Street in the Puente de Vallecas district around 2:00 a.m. Despite a thoracotomy and resuscitation efforts, he died. Police detained two alleged aggressors, also Spanish—one aged 19—who knew the victim and had no ties to street gangs. One of them had wounds to the neck and glute.
The second death happened at 5:40 a.m. on Alonso Cano Street in the Chamberí neighborhood, where a 63-year-old man of Bolivian origin was found with multiple wounds. After 40 minutes of advanced cardiopulmonary resuscitation, his death was certified. Police are investigating without a clear hypothesis on the motive.
These incidents highlight a surge in violence involving bladed weapons in the capital during the Christmas holidays.
