Have you seen missing teenager Riza Gjana?
The 17-year-old from Albania has been staying with a foster family temporarily but is believed to have left to try and find friends. He was last in contact on December 10.
Sergeant Lynda Lynch said, “We believe Riza could be in London but we need to know he is safe and well. He speaks very little English so needs help and support.
“If you have seen him or have any idea where he could be please contact us so we can get in touch with him.”
