Police are appealing for help finding a missing 16-year-old named Kyle who has not been seen for 10 days.
Scotland Yard issued a photo appeal on Wednesday, saying they are “growing increasingly concerned about his welfare”.
The teenager, whose surname has not been released, was last seen on Sunday, April 30. He is said to have links to the Slough and Bromley areas.
The Met says Thames Valley Police has been helping the force with its investigation.
A Met spokesperson said: “Kyle has been missing since Sunday 30 April and officers are growing increasingly concerned about his welfare.
“Kyle is 167cm or approximately 5ft6ins tall. He sometimes wears his hair in braids and may be wearing a blue bandana. He was wearing a black puffed jacket with colour on it, and grey Nike Jordan high top trainers.”
