Detectives are appealing for witnesses following the stabbing of a 15 year-old-boy in Wandsworth.

Officers on patrol came across two groups of males fighting outside Sainsbury’s on Garratt Lane, SW18 at around 4:58pm yesterday (October 29)

A boy, 15, was taken to hospital, where he later died. Although formal identification awaits, officers say his next of kin have been informed.

Two other victims, also aged 15, sustained injuries that are not believed to be life-threatening.

An investigation has now launched, with police appealing for witnesses.

So far two males have been arrested - a man, 19, on suspicion of GBH and a 17-year-old male on suspicion of affray.

Both are in police custody while enquiries into the circumstances continue.

Detective Vicky Tunstall, from the Met’s homicide team, said:

"My deepest condolences are with the family of this young man. I want to reassure them that my team and I are working to give them the answers they deserve.

“While our investigation is still in its early days, it would appear that an altercation occurred between two groups of males in the Garrett Lane area, outside Sainsbury’s, at around 4:50pm on Thursday evening. It was during this altercation that the victim was stabbed and sadly, later died.

“This was a busy area, very near to the shopping centre within Wandsworth. There will be people who saw or heard something suspicious that could help us to piece together the final moments for the victim and possibly identify who was responsible.

“It is these people we urgently need to speak to. I am appealing for any witnesses or anyone with information to call the incident room and share that information with police. All calls will be treated with sensitivity and confidentiality."
