Police say there is growing concern for a Goring teenager who has not been seen for almost three weeks.
Alisha Lynch, 18, left her home on Monday morning, January 7, to go to Northbrook College at Broadwater and has not been seen since.
Police and social services say they have concerns for the student and need to check on her welfare to make sure she is okay.
Alisha is described as white, 5ft 7inch tall, of medium build, with shoulder length, light brown hair and brown eyes. She was wearing a black short-sleeved top, black trousers and a dark blue winter coat.
Anyone who has seen her or has information about her whereabouts is asked to call Sussex Police on 101, quoting serial 1637 of 07/01.
