Empty caravans at a holiday village have been searched by volunteers looking for a missing student who has not been seen since Boxing Day.
Sophie Smith left her home in Gorleston, Norfolk, dressed in shorts and a vest top at 03:00 GMT.
On Friday, police said it was likely the 21-year-old had gone into the sea. The coastguard and police helicopter has searched the shoreline.
Caravans at the Hopton Holiday Village in Great Yarmouth were searched.
They also searched the area in and around Britannia Pier in Great Yarmouth.
Earlier, the Find Sophie Smith Facebook page said: “Both areas are huge, so we need as many people as possible. Anyone joining Yarmouth needs to wear appropriate clothing, it will be cold.”
The volunteers have liaised with the coastguard and have been told “these are the next two places that haven’t been checked inland”.
Ms Smith, who had been receiving treatment for depression and anxiety, is described as being white, about 5ft 8in (1.73m), of a slim build with shoulder length blonde hair.
It is believed she was wearing a dark-coloured vest top and light-coloured shorts.
