The family of a man who has been missing for more than six weeks travelled to Wakefield and watched as police divers searched a river.
A team of specialist police divers scoured the River Calder for father-of-two Damion Vernon, but found no clues as to the missing man’s whereabouts on Wednesday 14 January.
It comes after repeated appeals by Humberside Police for information to trace Mr Vernon failed to provide any leads.
Mr Vernon drove to Wakefield on 8 December after telling his family he was going to pick up a car.
Detectives said he left his blue Vauxhall Corsa, registration number YH51 FLL, parked on Sycamore Street, Belle Vue, in Wakefield.
He then left the vehicle and walked along an alleyway just off Sycamore Street which is close to the River Calder.
Mr Vernon’s brother, Aaron Vernon, 35, said: “We are shaking with worry and anxiety all the time about what might have happened.
“We are just paying they don’t pull him out of the river.”
Aaron also appealed directly to his brother to get in touch . He said: “No matter what the situation we just want Damion to come home.
“We’re a big enough family to sort whatever problems he got into - we just want to know he’s safe.”
Detective Chief Inspector Matthew Baldwin added: “We have now put out several appeals for information, but so far have drawn a blank.
“Our investigations have not found any sightings of Damion since he left his vehicle on Sycamore Street in Wakefield.
“We were hoping that our appeals would provide some information to us that would give us hope in finding him.
“We do not have any new specific intelligence to suggest that Damion has entered the River Calder but we are now having to look at the possibility that this may be the case. We are now in a situation where we must search the waterways surrounding the areas where Damion was last seen.”
It comes after Humberside Police released images of the car in which Damion travelled to Wakefield, in the hope it could help trace of the missing father
The route he took was along the A164 to Howden, then onto the M62 leaving at Junction 31, onto the A655, turning left at the traffic lights onto the A645 and into the BP filling Station then back out onto the A645 towards Wakefield.
He then continued towards Wakefield on the A638 Doncaster Road before turning right into Elm Tree Road and immediate left onto Sycamore Street.
Mr Vernon is described as six feet tall, slim and has short wavy light brown-coloured hair.
Images of Damion in Bridlington bank were also released and were taken on the day of his disappearance.
He was last seen wearing a mustard-coloured bodywarmer, a green long-sleeved woollen jumper and jeans.
