The SIU is looking for witnesses after this week’s OPP take-down of a suspected drunk driver on the 401. 
Elgin OPP got a complaint Tuesday afternoon about a transport weaving in and out of the eastbound lanes of the highway near Dutton.
When the driver wouldn’t pull over, officers used a “moving containment” maneuver to bring a truck to a stop in London.
Authorities now say the 38-year-old got into a scuffle with officers while being removed from the vehicle, and had to be taken to hospital for treatment of a foot injury.
The Special Investigations Unit is called in to probe any situation involving police when there has been an injury or death.
