Madison police arrested a man Monday after a traffic stop that resulted in the discovery of methamphetamine.

Officers made a traffic stop in the 600 block of Clifty Drive for a broken taillight. Driving the car was Douglas W. Gray, 30, of Madison.

Officer Kurtis Wallace, who stopped the vehicle, had seen records of purchases of pseudoephedrine in Madison made by Gray earlier in the day, Chief Dan Thurston said.

A K9 open-air search of the vehicle led to the discovery of narcotics in the vehicle, Thurston said. Officers located a black sunglasses holder that contained a glass-smoking device, aluminum foil and a straw, Thurston said. The glass pipe contained a white residue, which was later swabbed and field-tested positive for methamphetamine, according to police.

During an interview with police, Gray denied any knowledge of the narcotics and said he threw away most of the pseudoephedrine boxes he recently purchased, Thurston said. Gray told police he threw the boxes away because he wanted to mess with police while they reviewed pseudoephedrine purchases.

Gray was arrested on charges of possession of meth and possession of paraphernalia. He was taken to the Jefferson County Jail.
