A convicted sex offender is being released from Headingley Correctional Centre on Thursday, police in Manitoba are warning.

Fabian Claybren Maytwayashing is considered at a high risk to re-offend, despite having received some treatment in the past, says the Manitoba Integrated High Risk Sex Offender Unit, a joint forces unit of Winnipeg police and RCMP.

He is leaving the jail after finishing his sentence for three counts of failing to comply with probation orders and bond conditions. Police say he is expected to live in Winnipeg.

The 41-year-old has a long criminal history that includes assaulting women with a weapon, uttering threats, assault, cruelty to animals and harassing individuals on the phone, said police.

One of his past convictions includes grabbing an unknown 14-year-old girl as she was walking home, dragging her into a yard, holding a knife to her throat and sexually assaulting her, said police.

He was sentenced to five years for the violent sexual assault in 2001.

Maytwayashing goes by a number of aliases, including James Henry Hildenbrand, Stephane Masters, Fabian Sennie and Fabian Choken.

Police said he frequently uses fake names to communicate with women on social media.
