A 76-year-old grandmother says she's suing the Cape Breton regional police force after officers stormed her house in a fruitless search for drugs and weapons.

Abbie Deveaux said her furniture was broken and the doors of her Sydney home were destroyed in Friday's raid.

"Those animals came in with the things on their faces hollering, 'Get down on the floor, get down on the floor,'" she told CBC News on Tuesday.

A dozen officers with the drug squad knocked on Deveaux's doors Friday morning, looking for cocaine and her 23-year-old grandson.

The doors were not locked and the police didn't find any drugs, Deveaux said, adding she's filing a complaint and a lawsuit.

"They darn well should fix my doors and fix what they broke," she said. "The nerve of them."

The police will not pay for anything, said Cape Breton regional police Chief Dave Wilson.

Wilson said investigators had information that there were drugs in the house and possibly a gun, and did what they had to do.

"If somebody knows that you're coming and there is a gun in the house, they're going to be waiting in the house with a gun aimed at the police officer," he said. "So when we go in a house, we take down everybody as fast as we can."

Friday's raid was one of a series of raids in the region in a police crackdown on street-level drug trafficking.
