Sexual predator recaptured by Montreal police

Montreal police have recaptured a dangerous sexual predator who escaped from the Philippe-Pinel Institute while on a supervised group outing on Tuesday.

Roger Lee Desmarais, 30, was arrested this afternoon at Émilie-Gamelin Place in downtown Montreal.

Police said they were notified by a citizen who spotted the man and recognized him.

Desmarais has been detained at the Pinel Institute since 2011. He escaped custody on a bicycle Tuesday afternoon.

Of 11,424 supervised outings over the past year, there were 21 escapes.

Desmarais was considered to be at high risk of reoffending, because of a long history of sexual assaults.
