Police are asking the public to be on the look out for a high-risk Edmonton sex offender who slipped away from his electronic monitoring bracelet Tuesday.

Michael Sean Stanley, 48, left Edmonton Tuesday morning for Lloydminster where he managed to cut off his electronic monitoring bracelet, leaving it on the roof of a local business.

Police say Stanley has a long history of sexual offences, including taking children from playgrounds.

Stanley is described as 5'9", 190 lbs, with black hair and brown eyes. 

He may be driving a purple 1996 Chevrolet Trail Blazer possibly with the Alberta plate BHD 1954. 

Stanley can be violent and should not be approached, police said.
