A 17 year old Spanish boy died yesterday afternoon after being stabbed outside a pub in San Sebastián de los Reyes (Madrid) during a night out with friends.

Eye-witnesses explained that, shortly before the stabbing, there had been a brief argument between the victim and his friends and a group of young South Americans.

Some say that the perpetrator spoke with a Mexican accent.

No arrests have yet been made.

The incident occurred at around 2.30am on the pavement outside the 'Image' pub on the calle Postas.

The victim was stabbed once through the left side of his upper chest, and was pronounced dead shortly before 4pm yesterday afternoon at the Infanta Sofía Hospital.

He becomes the fifth person murdered during nights out in and around the capital since the start of the year.
