Concern is growing for a North Lincolnshire man who left his home in Wroxham Avenue in a distressed state more than an hour ago, wearing just his pyjamas.
David Doyle, 30, left the house at around 1.15pm and walked in the direction of Evesham Avenue in Grimsby.
He did not take any money or his medication with him and despite extensive searches by officers and his family, he is yet to be traced.
He is described as white, around 6ft tall, with a shaved head, beard and glasses.
He has tattoos on his arms and wore a yellow Family Guy T-shirt, Marvel pyjama bottoms and red trainers. He did not have a coat.
Inspector Neil Hutchins said: “Mr Doyle has a number of medical conditions but did not take any of his medication.
“He has been missing before and has attempted to travel to the Lincoln area.
“If anyone has seen him, we would urge them to call 101, quoting log number 211 of January 12.”
