Saskatoon police described the 42-year-old man as five feet 11 inches and approximately 155 pounds. He was said to have short black hair, brown eyes and several tattoos.
A public notification issued last year, by the Winnipeg Police Service and Manitoba Integrated High Risk Sex Offender Unit, said his tattoos include a cross on his neck, text that reads “Kim” on his chest and a full sleeve with a feather on his left arm. Perswain was also said to be inked on his back, upper torso, left leg, and body, as well as on both of his arms and hands.
Perswain is forbade from visiting places where people younger than 16 years old may congregate, such as public parks, community centres and schoolyards. He is also not allowed to have contact with anyone those under 16 and is prohibited from buying, using or possessing alcohol or other intoxicants, Saskatoon police said.
SPS noted that vigilantism against the man will not be tolerated.
