Dog dies falling in frozen lake

Emergency services have issued a safety warning after a dog died and two men were injured falling through a frozen lake in Hertfordshire.

The separate incidents happened at Fairlands Valley lake in Stevenage on Tuesday where staff at the site broke through the ice to retrieve the dog.

Firefighters and paramedics used oxygen and heart massage to try to revive the animal but attempts were unsuccessful.

The two men were treated in hospital following their ordeal.

Gary Sanderson, from the East of England Ambulance Service, said: "On this occasion the two lads were very lucky to crawl out to a place of safety.

"We urge the public to stay well away from anywhere which is frozen over."

Dave Harold, fire service district commander for Stevenage and North Hertfordshire, added: "This tragic incident highlights the dangers of walking across frozen lakes, both for people and animals.

"It's impossible to tell how thick the ice is and how deep the water is underneath, and our advice is to stay well clear."
