A member of a Winnipeg Hells Angels gang who was shot six times on Thursday by an unknown assailant is refusing to co-operate with police.

Rodney Patrick Sweeney, who police say is in stable condition, is refusing to work with officers from the city's major crimes and gang units.

Sweeney was driving in his tow truck with his two-year-old son on a residential street when he was shot in the chest, shoulders and leg. A bullet also grazed the side of his head. His son was not injured.

A suspect fled on a motorcycle and has not been apprehended by police.

"It wasn't a random shooting, I'm sure," Insp. Stan Tataryn of the Winnipeg police said. "This was a case of taking care of business."

Police did charge three men linked to the biker gang who were caught for speeding en route to the hospital to see Sweeney. Police charged them with possessing a small amount of cocaine.

Last year, Sweeney was the subject of a Canada-wide warrant related to the beating of another biker.

A large gathering of Hells Angels is expected in Winnipeg next month.
