Police are appealing for witnesses to come forward after a teenager was fatally stabbed in Lewisham.

Officers were called to Sharratt Street in New Cross on August 3 after 19-year-old Andrew Oteng-Owusu was knifed.

He was then taken King’s College Hospital, but died there the following morning.

A post-mortem examination has shown that death was caused by a single stab wound.

Detective Inspector Mick Norman, leading officer on this investigation, said: “Officers have already spoken with many local people, who have provided helpful information. Andrew has been described as a ‘gentle giant’ who was clearly well liked on the Lovelinch Estate and provided a good deal of support for his mother.”

Norman also said that the police are still lacking further information in link with the murder.

“In particular, I want to speak with two key witnesses – one of whom assisted Andrew after he was attacked, and another who helped police near to the scene”, he added.

“The first is a young black man who, after the stabbing, walked with Andrew to the block of flats where he lived. He is aged in his late teens or early to mid-20s and was wearing a white t-shirt.

“The second key witness – also a black man of similar age – was riding a moped and directed police into the estate to the area where Andrew had collapsed. He was wearing grey clothing.”

No arrests have been made in connection with this incident.

Those with information are urged to contact the police by calling Lewisham Police Station on 020 8721 4961 or Crimestoppers on 0800 555 111.
