Searches are continuing for a 21-year-old student who went missing in the early hours of Boxing Day after police said that it was "most likely" that she has gone into the sea.

Sophie Smith, who was suffering from depression, did not have her phone with her and has not accessed her bank or social media accounts since leaving home.

She was believed to be wearing only a vest and shorts when she left her home in Gorleston, near Great Yarmouth, Norfolk, at around 3am on December 26.

Norfolk Police said further sea and coastline searches would take place on Friday. Volunteers are expected to be out in force over the weekend in an area near Hopton Holiday Village and Britannia Pier in nearby Great Yarmouth.

Organisers wrote on the Find Sophie Smith Facebook page: "Both areas are huge, so we need as many people as possible. Anyone joining Yarmouth needs to wear appropriate clothing, it will be cold."
