Appeal after teenager stabbed to death in London
Detectives investigating the murder of a teenager have appealed for witnesses to come forward.
The 18-year-old victim was stabbed to death outside a convenience store in Borough, south east London, on Friday afternoon.
Police are looking for a suspect described as a short dark-skinned black man, with short dreadlocked hair, wearing a white short sleeved top, dark-coloured trousers and dark-coloured footwear.
Officers said they are keeping an open mind about the motive of the attack, which happened at around 2.30pm outside the Quality Food store on Pilgrimage Street.
An 18-year-old from Southwark has been arrested on suspicion of perverting the course of justice and is in custody at a south London police station.
A post-mortem examination carried out at Greenwich Mortuary yesterday gave the victim's cause of death as stab wounds.
Detectives from the Metropolitan Police's Homicide and Major Crime Command have opened an incident room in Lewisham.
On Friday, Simon Hughes, justice minister and Liberal Democrat MP for Bermondsey and Old Southwark, described the stabbing as an "awful tragedy" and appealed for calm.
He said: "Any attack like this has no justification in our borough or city and I call on everyone, particularly young people in Southwark or elsewhere who knew the victim, to restrain themselves from any further action which might make matters even worse."
