Police divers have been combing a stretch of river as they search for a man missing from his home.
Graham Clark, 54, was last seen by his mother at her home in the Knightswood area of Glasgow at about 6am on Tuesday.
Less than half an hour later, his car, a green Mazda, was found abandoned on the southbound carriageway of the city's Kingston Bridge.
Divers could be seen searching an area underneath the bridge on Wednesday after they began their search of the River Clyde on Tuesday.
Officers are appealing to the public for help in connection with their inquiry.
Mr Clark, of Moorpark, Renfrew, is described as white, around 6ft tall and of medium build. He has light brown closely-cut hair and wears glasses.
Chief Inspector Simon Wright said: "My officers are currently investigating Graham's disappearance and one line of inquiry is that he has fallen into the water after stopping his vehicle on the Kingston Bridge, and a full search of the water is being carried out by police divers with assistance from our partners.
"At this time I would urge any motorists who may have seen either Mr Clark or his car stopping on the Kingston Bridge around 6.20am on Tuesday to contact Johnstone Police through 101."
