CCTV images of possible witnesses released over missing surfer Oliver Doy
Images have been released of people police want to speak to after a surfer went missing in Newquay.
Oliver Doy, 26, from Hook, Hampshire, was last seen walking with an unknown man and two women near the town's cinema early on Saturday.
Coastguard rescue teams and a lifeboat were called to search for Mr Doy whose driving licence was found on a beach.
Police said they wanted to speak to a woman and a small group of people who were all captured on the footage.
A spokesman for the force said they were becoming "increasingly concerned" for Mr Doy as time went by.
He urged members of the public to be vigilant when out walking on the beaches or coastal paths for clothing or personal items which may be linked to the surfer.
Mr Doy had been working as an NHS healthcare assistant after having graduated from Plymouth University, and was in Newquay on holiday with some friends.
