A large search effort is underway to find a man with dementia who has gone missing in Merseyside.
Thomas Cook is 76 and from Liverpool.
Police say they were called out to reports of an elderly man stuck in the mud along the river Mersey around Runcorn. Extensive searches are underway in the area involving two police forces and the coast guard - though officers are also appealing for people to keep an eye out for Mr Cook elsewhere.
He was last seen wearing a grey Nike tracksuit, walking boots, a black body warmer and black glasses.
