Police are urgently appealing for the public's help in tracing a missing man from Dewsbury.
Colin Vasey, aged 81, was reported missing from his home address on Sunday 17 November and was last pictured at 5.53am walking on Leeds Road towards the ring road in Dewsbury.
Earlier footage released is believed to show Mr Vasey walking on the Owl Road, Shaw Cross area of Dewsbury at 5:30am.
An extensive search operation has been running throughout the week with officers looking for Colin with the help of specialist search dogs and a drone.
Despite these efforts the search team have been unable to locate him, and officers are becoming very concerned for his welfare – especially after the recent freezing cold temperatures.
Colin is thought to be wearing a blue fleece, grey pyjama bottoms and a dark coloured beanie hat.
Regarding the ongoing search, Detective Inspector Stephanie Fox of Kirklees Crimes Investigation Department 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.”
