Police are searching for a vulnerable teenager who they fear may be at risk of being criminally exploited in Greenwich or Woolwich.

Osei Bonsu, 17, was last seen by his mother in Staines-upon-Thames on September 29, but is believed to have been seen in the Northumberland Park, Tottenham area, with friends in the last few days. He also has links to Greenwich and Woolwich.

He is described as black, of medium build with short black hair and was last seen wearing blue jeans, white trainers and a black jacket, carrying a small bag.

Officers are keen to speak to anyone who has seen Osei in the last week, knows where he is, or knows anyone who may have had contact with him.

Anyone with information is asked to contact Surrey Police on 101, quoting reference PR/45190103872 - in an emergency please call 999.

If you do not wish to leave your name, please call the independent charity Crimestoppers on 0800 555 111.
