Police attempting to locate traces of missing man Ian Gibbon have this morning begun to search the River Esk and Whitby Harbour.
Mr Gibbon has not been seen since he left his home at around 10pm on Friday December 27.
His silver Vauxhall Zafira was found at Larpool Lane near to the viaduct early the following morning.
In the days since, Whitby Coastguard and Scarborough and Ryedale Mountain Rescue team have searched the woods around Larpool, with no success.
Police have now switched their attention to the Esk and are using specialist search equipment.
