Oxford St victim 'stabbed in heart'
A teenager killed in front of horrified shoppers at the Boxing Day sales died from a "single stab wound to the heart", police have said.
Seydou Diarrassouba, 18, was stabbed to death on Monday in broad daylight following a fight at a Foot Locker sports shoe store on London's Oxford Street. Just hours later another youth was stabbed in the leg on the same busy street.
After a post-mortem examination was conducted at Westminster Mortuary on Tuesday, police said that Mr Diarrassouba - also known by the nickname "Nutz" - had died from a single stab wound which pierced his heart.
Eleven suspects - including two 22-year-olds, five 19-year-olds, three 17-year-olds and one 16-year-old - are being held in custody in several London police stations in connection with the incident.
The motives for the confrontation between the two groups of youths inside Foot Locker remain unclear. Police said they were particularly interested in obtaining videos of the incident shot on camera phones.
Speaking outside Scotland Yard today, Detective Superintendent John Sweeney from the Metropolitan Police's Homicide and Serious Crime Command said: "There were several people who witnessed this event, both inside and outside the store.
"A number of them recorded it on camera phones, and we're particularly interested in those people coming forward so we have access to that footage."
School friend Munawar Shaikh, 20, today described the dead youth as a "big personality" who always had a smile on his face. The pair grew up together in Mitcham, south west London and attended Rutlish School at the same time.
Mr Shaikh said: "I heard about it on social network sites. It's devastating, I had lost contact with Seydou but he was such a big personality and a person everyone in Mitcham would know. He was just a good kid who always had a smile on his face."
Tributes to the dead teenager poured in throughout the day on a Facebook page called R.I.P. Seydou. Witnesses to the stabbings can contact police at the incident room on 020 8721 4906 or Crimestoppers on 0800 555 111.
