There are no plans to relaunch the search for a passenger reported missing when a ferry arrived in the North East.
HM Coastguard has confirmed it will not pick up the search again this morning after it was stood down at 7.30pm yesterday.
The service said the matter was now in the hands of Northumbria Police.
The Coastguard was alerted to a man in his 60s going missing on a DFDS ferry from Amsterdam to North Shields, North Tyneside, at 12.15pm yesterday.
The HM Coastguard search and rescue helicopter based at Humberside was sent to the area and was searching with lifeboats from RNLI stations including Filey, Scarborough, Whitby, Hartlepool, Tynemouth and Blyth.
A Mayday relay broadcast has been issued by HM Coastguard to inform all vessels in the area and Northumbria Police has been notified.
A force spokesman said: "The passenger, a foreign national aged in his 60s, was travelling on board the ferry but did not depart the vessel upon arrival in North Shields and cannot be found on board.
"Inquiries are ongoing to trace the man, contact his next of kin and establish the circumstances around his disappearance."
A spokesman for Sunderland Coastguard Rescue Team said: "The team were paged to take part in a full scale coastal search for a person reported to be overboard from a DFDS ferry after their belongings were found still onboard after its arrival in North Shields.
"Ourselves, Blyth, Seaham and Voluntary Life Brigades from South Shields and Tynemouth conducted a full coastal search of beaches and coves from Seaham in the south to Cambois in the north.
