Iowa City police arrested a man after allegedly finding marijuana on him during a traffic stop.

Oudone Koulavongsa, 31, 721 Pepper Drive, was charged Oct. 26 with possession of marijuana and operating while intoxicated.

According to complaints, Koulavongsa was stopped by police for driving 37 mph in a 25-mph zone, when a canine detected narcotics inside the car.

Upon contact with police, Koulavongsa allegedly said he "was in trouble," and was "s*** faced." The complaint said the defendant also told officers he had been consuming alcohol.

During a search, officers allegedly located a jar containing one ounce of a substance that appeared to be marijuana, packing material, and a digital scale.

Koulavongsa allegedly admitted the marijuana belonged to him.

The complaint said the defendant performed poorly on field sobriety tests and blew a .08 in a preliminary breath test.
