As the manhunt for a high-risk sex offender continued in western Saskatchewan Friday, more information emerged about Michael Sean Stanley, 48.

Eight schools in the Kindersley area were on a partial lockdown Friday, after a number of unconfirmed sightings of Stanley were reported to police. Schools in Rosetown were on alert as well.

Police in Lethbridge, Alta., were also on high alert after an unsubstantiated sighting of Stanley in that city. 

RCMP put out a warning on Tuesday after Stanley's electronic monitoring bracelet was found in Lloydminster. 

Assault, sexual assault convictions on record

Police said the Edmonton man has a history of taking children from playgrounds. In 2006, he was sentenced to time behind bars for assault and unlawful confinement after luring two mentally impaired boys to an Edmonton apartment. One boy was 13, and one was nine. 

Court heard he smoked crack and blew smoke in their faces.

He spent nine years in prison for the aggravated sexual assault, in the late 1980s, of an 82-year-old Lethbridge woman who was confined to a wheelchair.

'Horrendous record,' court told

Court records say Stanley has a "horrendous record" with numerous convictions going back to 1987. He suffers from a severe personality disorder and is a high risk to reoffend, court has been told.

Stanley is five feet, nine inches tall, weighs 190 pounds and has black hair and brown eyes.

He may be driving a purple 1996 Chevrolet Trailblazer with Alberta plate BHD1954.

Police said that anybody who sees Stanley should not try to approach him, as he is known to be violent. Instead, they are asked to contact the nearest police service.
