Search for Samuel Campbell in north Antrim continues
Police have said they are very concerned about a missing County Antrim cyclist, but are hopeful he is still alive.
Samuel Campbell, 49, went out for a bike ride in the Kells area at 14:15 GMT on Sunday and failed to return.
Det Insp Bob Blemmings, who is leading the search for Mr Campbell, said it would be very unusual for him not to contact his family
He said police were following a number of lines of inquiry.
These include that Mr Campbell had become ill or had had an accident.
"He was last seen wearing a red top with the symbol TCG, black cycling leggings and cycle glasses," Det Insp Blemmings said.
"We're very concerned about his whereabouts, but at the moment we just don't have enough information.
"That is why we are really asking did anyone who saw or knows Mr Campbell and had seen him in the last day or two days and could give us information on his whereabouts to contact us in Ballymena."
The detective said that Mr Campbell would often cover about 20 miles on his bike rides so the search for him is covering a wide area, including Kells, Ballymena, Clough, Ahoghill and Cullybackey.
He appealed for farmers in the area to check outbuildings and laneways.
The Irish coastguard helicopter was involved in the search operation but has since returned to base.
