BRIDGEPORT, W.Va. - A man was arrested after mistakenly handing officers meth instead of his registration at a routine traffic stop.

Officers stopped Roy Porter, 57, on account of his vehicle having improper registration, according to WBOY. Porter handed authorities a small paper packet, believing it to be his paperwork, but a small bag holding a "crystal-like substance" fell out, according to authorities.

The Bridgeport Police Department led a K9 unit around the area that detected drugs in Porter's car.

Porter and the single passenger in the vehicle were both arrested after being found in possession of a half-pound of meth.
