A high-risk offender, who was released on Oct. 11 in Durham Region, has been arrested after allegedly breaching his court-imposed curfew conditions.

Keith Theodore Constantin, who is 48, has a history of serious criminal convictions, including sexual assault, sexual assault with a weapon, assault with a weapon, assault, robbery, possession of explosives, uttering threats, and multiple violations of probation orders.

On Oct. 10, Durham Regional Police Service (DRPS) issued a public safety alert about his release, saying that he “poses a significant risk to the community, especially children.”

Constantin was bound by several conditions, including wearing a GPS monitoring device, abiding by a curfew, and not communicating or engaging in any activities with anyone under 16 years old.

He was also required to not be present in any daycare, swimming area, school ground, or playground where one might reasonably expect children to be present, or any community centre where children under 16 are present.

The offender was also not allowed to go to any public place, such as a mall, where persons under the age of 16 are present.

On Monday, Constantin breached the conditions of his release and was taken into custody.

He was held for a bail hearing and remains in custody.

Anyone with further information about this high-risk offender is asked to contact the Offender Management Unit at 1-888-579-1520, ext. 5357, or Crime Stoppers anonymously.
