Police investigation launched after debris thrown from A500 bridge.
It's happened multiple times in Willaston earlier this week.
Police are appealing for witnesses after concrete blocks and bricks were dropped off a bridge near Crewe.
It was over the A500 between Cheerbrook and the Shavington roundabout, between the 2nd and 4th of January.
Bricks or concrete have been dropped from the bridge onto passing cars causing damage, and in one case, resulting in a collision. The incidents appear to happen between 3.30am and 6am.
Sgt Steve Tandy said:
“On 3 January an officer attending the report of a car being damaged was injured along with the person reporting the damage, after a van collided with the officer’s stationary patrol car.
"Both were standing away from the cars on the grass verge but the collision resulted in them being injured following the impact. Thankfully the injuries weren’t serious, but this could have been much worse.
“Not only that, the shock and distraction of a concrete block or brick landing on your vehicle could also cause a serious collision.
"Whoever is doing this is putting people at serious risk of harm and is breaking the law - you will be dealt with robustly.
