A 54-year-old man was heading to court to face a drunk driving charge when he was pulled over by police for impaired driving, AM 980 reported.
Aurora resident Kin-Ping Ma now faces multiple new charges.
He was on his way to a Chatham court last week to face charges laid by the Ontario Provincial Police in April.
He had been charged with impaired driving and exceeding the legal limit of alcohol. Ma had also been suspended from driving.
When police pulled him over for erratic driving last Friday, he was charged with impaired driving, operating a motor vehicle over 80 and driving while under suspension.
He will appear in a St. Thomas court on July 23.
