A 32-year-old Pickering man has been charged with three counts of mischief endangering lives after concrete cinderblocks were thrown from an overpass onto Highway 401 in three separate incidents.

“When people are throwing not just bricks, but full cinderblock pieces of cement off of a overpass onto traffic below, the results can be absolutely deadly and catastrophic,” said Ontario Provincial Police spokesperson Sgt. Kerry Schmidt.

The first report of the falling cinderblock came at around 10 p.m. on Sunday when a vehicle was struck under the Progress Rd. overpass on Hwy. 401, Schmidt said.

Images posted by Schmidt on his Twitter account shows a vehicle with a hole in the roof after concrete pierced through to the passenger side. The driver of the vehicle was not injured.

At around 11:15 a.m. on Wednesday, police received another call about concrete falling from the Yonge St. overpass on Hwy. 401.

About an hour later, police responded to more cement falling from the Warden Ave. overpass.

A witness had seen suspicious activity on an overpass along the highway and took photos of the person and vehicle involved.

Everton Emmanuel James appeared in court Thursday morning.
