A man has been found dead in deep snow by a farmer, while emergency services struggled to reach the area because of adverse weather conditions.
The 27-year-old was found in Brierfield near Burnley. It is thought he died on Saturday while making his way home after a night out with friends.
"Early indications suggest that it appears to be a very tragic incident where a young man has been out with friends and has become caught up in the weather last night on his journey home," Chief Inspector Derry Crorken told Sky News.
"The snow and ice has been severe in the area with many roads not passable. I would urge people to take precautions and only go out if it is necessary.
"If you do go out, then make sure friends and family know where you are and that you have suitable clothing on and your phone with you."
It is believed to be the second weather-related death in the last few days.
