A girl who has been missing for three weeks may be in Oxford.

Police said Amran Yusuf left her home in Lozells, Birmingham on July 2.

The 15-year-old made intermittent contact with her family until last Sunday but they have not heard from her since then and are very worried.

She has been missing before but not for as long as on this occasion.

Officers said she is known to travel around the country and was last seen by a friend in Oxford on Wednesday.

She is black, 5ft 7ins tall and is of a stocky build.

She has shoulder length straight black hair and wears glasses.

Anyone with information should call police on 101 or the Missing People charity anonymously on 116 000.
