A pregnant British woman, her husband and their 3-year-old son were killed in a house fire early Sunday as police who arrived before the fire brigade prevented neighbors from trying to save them.

“Please save my kids," the woman screamed from a bedroom window and neighbors tried to help but were beaten back by flames and were told by police not to attempt a rescue.

By the time firefighters got into the house in Doncaster, Michelle Colly, 25, her husband, Mark, 29, and son, Louis, 3, were dead. Their daughter, Sophie, 5, was taken to hospital and believed to be critically ill.

“It was the most harrowing thing I have ever witnessed. Michelle was at the bedroom window yelling, ‘Please save my kids’ and we wanted to help but the police were pushing us back and not allowing us near," said Davey Davis, 38, a friend of the family. "We were willing to risk our lives to save those kiddies but the police wouldn’t let us."

“Tempers were running very high, particularly with the women who were there, but the police were just saying we have to wait for the fire brigade because of health and safety."
