An air and sea search has been launched after a man was reported missing from an oil rig in the North Sea.
The alarm was raised after the 49-year-old, who was working on the Noble Lloyd Noble installation, could not be located on board.
Police were alerted to his mysterious disappearance from the rig, which is located in Mariner Field, about 90 miles east of Shetland, at about 9.20pm on Tuesday.
Following initial searches of the installation, a search involving a rescue helicopter, the coastguard, two supply vessels and a platform supply vessel began.
Inspector Steve McEwan of Police Scotland said: "An extensive search of the rig itself and the water surrounding it is ongoing, led by the Maritime and Coastguard Agency (MCA).
"This involves the use of a search and rescue helicopter, two standby vessels and a platform supply vessel.
"We are working closely with the companies involved and next of kin to keep them informed of any developments."
