POLICE searching for missing school deputy head Mark Bushnell have scoured a popular caravan park.
The father-of-three, from Durham City, was reportedly spotted by a member of the public at Crimdon Dene on the County Durham coast.
The caller told police they saw a man matching the description of 50-year-old Mr Bushnell at 8am on Monday (March 10) at the Crimdon Caravan Park.

"We have informed Mark's family of this sighting and are continuing to follow a number of lines of enquiry.
"Specialist teams are concentrating their searches from Crimdon Caravan Park towards the stables at Crimdon Dene.

Mr Bushnell spent Saturday in London watching the school rugby team, which included his eldest son Jacob, in a cup semi-final.
He left home on Sunday morning to take some washing to a launderette because the family washing machine was broken.
His car, a grey Citroen C3, was found at Blackhall Rocks early on Monday morning .
After police issued an appeal for help, walkers said they saw him at Blackhall Rocks on Sunday.
The coastline from Seaham to Hartlepool has been searched with the help of other organisations, including the Coastguard.
