We are increasingly concerned for the welfare of 16-year-old Mia Thornton, who was last seen on the morning on January 21 at an address in Clun Road, Littlehampton.
Mia has a serious injury to her hand that needs medical attention, and so we are very keen to find her to make sure she is safe and well.
She is described as 5'3", of slim build with brown shoulder-length hair that she often wears in a bun. She was last seen wearing black skinny jeans, a mustard coloured puffer jacket and trainers with a clear bubble on the heel.
Anyone with any information is asked to contact police quoting serial 1079 of 21/01.
