Convicted sex offender Michael Sean Stanley is likely somewhere in southern Alberta, Lethbridge police said at a news conference Tuesday morning.

Police in several provinces have been searching for Stanley since he cut off his electronic monitoring bracelet on Oct. 1 in Lloydminster, located on the Alberta and Saskatchewan border.

Stanley contacted family in Lethbridge on Friday, police said. A vehicle belonging to the 48-year-old man was seized in the west end of the city on Monday.

There have also been numerous unconfirmed sightings of Stanley, police said.

The Edmonton man has a lengthy criminal past including assaults and sexual assaults, and is considered a high risk to reoffend.

Stanley 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 boys with mental impairments — who were age nine and 13 — to an Edmonton apartment.

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

“This is a general message to everybody to be safe, be wary. He has offended against all ages, all persons,” said Lethbridge police Staff Sgt. Ian Sanderson.

Wanted posters are being placed around Lethbridge and schools will be sending children home with notices for their parents about Stanley's possible presence in the community.

Stanley is described as five feet nine inches tall, 190 pounds, with black hair and brown eyes.

He was released from prison in April 2011 after completing a 32-month sentence for assault and forcible confinement.

One of the conditions of his release was that he wear an electronic monitoring bracelet.
