West Yorkshire Police have stepped up their efforts to find a missing pensioner from Yorkshire by utilising drones and specialist search dogs.
Colin Vasey, 81, from Dewsbury, has been missing since Sunday, November 17 and police are growing increasingly concerned for his welfare, with temperatures plummeting below freezing this week.
The CCTV footage above shows Mr Vasey's last-known movements, and shows him walking along Owl Road in Shaw Cross, Dewsbury, at 5:30am on Sunday morning.
He has not been seen since and the force has launched an extensive search operation in a bid to find him.
Colin is thought to be wearing a blue fleece, grey pyjama bottoms and a dark coloured beanie hat.
Detective Inspector Stephanie Fox of Kirklees CID, said: "We desperately need to find Colin and reunite him with his family. There is an extensive search operation in place and I am again appealing directly to anyone who sees Colin or thinks they might have seen him to get in contact
"He is an elderly gentleman wearing clothes that are unsuitable for the harsh conditions.
"We have had a lot of people who want to help find Colin and would like to thank the community for their help.
"Any small amount of information could really help us and our specialist teams currently out looking for him."
Officers are also appealing for anyone who was in the area of Owl Lane at around 05:30am on Sunday to get in touch - particularly drivers who may have dash cam footage.
