Saskatchewan Sightings Of Michael Sean Stanley, Missing Sex Offender, Not Confirmed: RCMP

KINDERSLEY, Sask. - Schools in several west-central Saskatchewan communities remain on alert as RCMP search for a potentially violent high-risk sex offender.

The Sun West School Division says RCMP advised Friday that eight schools in Kindersley and the surrounding area should stay in what police call "hold and secure" mode until the end of the day as a precaution.

"Hold and secure" mode means students are kept inside and doors are locked.

The precautionary measures were put in place Thursday following unconfirmed sightings of Michael Sean Stanley in the region.

Stanley, who has a long history of sex offences including taking children from playgrounds, cut off his electronic monitoring bracelet Tuesday in Lloydminster.

RCMP say they've had more than 10 reported sightings of Stanley in Saskatchewan, but none have been confirmed and several have been proven false.

Stanley is on Alberta's high-risk offender list.

He was released from jail in April 2011 after completing a 32-month sentence for assault and forcible confinement, according to Edmonton police at the time.

That advisory said Stanley is considered by police to be "an untreated violent and sexual offender who poses a risk of significant harm to the community."

Stanley was being monitored by police under a peace bond, which authorities can get to impose conditions on individuals in the community.

His peace bond has 20 conditions, including that he stay away from children.
