KINGSTON, Ont. -- A 36-year-old Oshawa man may be watching his back more closely after a bag of crystal meth that got stuck to that part of his body resulted in his arrest.

Police in Kingston, Ont. say they were asked to find the man after his girlfriend's family expressed concern for her safety.

They tracked the couple down to a Kingston motel and found her safe and sound, but grew suspicious of the man when they saw the bag of drugs stuck to his sweaty back.

A search of the room turned up more crystal meth, a fentanyl patch, marijuana and at least $5,000 in cash.

Police say the man is facing five charges including possession for the purpose of trafficking and uttering threats.

He is being held in custody in a Kingston jail.
