Lifeboats crews and a helicopter are carrying out a "massive search" for an angler who has been missing overnight.
Humberside Police said Nigel Savage, 49, was reported missing after he failed to return home from a fishing trip near Scarborough, North Yorkshire, with his two springer spaniel dogs.
Mr Savage, from Beverley, East Yorkshire, went to the coast in his green Peugeot 206 car which was found in a lay-by at Crook Ness, Field Lane, Burniston, at 3.26am today.
His two dogs were traced at the cliffs nearby.
A force spokesman said Mr Savage's rucksack and some fishing tackle were also discovered on the cliffs.
He said a woman saw the dogs and rucksack at the location at 4pm yesterday but did not see Mr Savage in the area.
The Maritime and Coastguard Agency (MCA) said a "massive land and sea search is taking place".
A search and rescue helicopter from RAF Boulmer in Northumberland, RNLI inshore and offshore lifeboats from Scarborough, along with Coastguard rescue teams from Scarborough, Burniston and Ravenscar have been involved in the operation.
