LONDON, Ont. - Provincial police say they're looking for four suspects after an officer was dragged by a vehicle during a traffic stop.

They say the officer stopped an SUV early Friday for allegedly driving the wrong way on a road in London, Ont.

The officer suffered minor injuries and was released after treatment at a London hospital.

OPP say they are looking for a grey 2014 Ford Edge that at the time of the stop had the licence plate BVKC 355.

The suspects are identified as three men and a woman.
