Police have warned parents to 'get a grip of your kids' after rocks were hurled at cars from a motorway bridge.
Four vehicles were damaged on the M66 near Bury and Heywood yesterday afternoon.
North West Motorway Police tweeted a picture of one vehicle with a fist-sized hole in the windscreen and said it was lucky 'no-one was injured or at worst lost their life'.
The rocks were thrown from the East Lancs Railway Bridge near junction two.
North West Motorway Police tweeted: "Do you know where your children are?
"No, we can oblige, your children are on a bridge above the motorway throwing boulders onto unsuspecting passing motorists, this time no one was injured or at worst lost their life.
"Four vehicles in total have damage #getagripofyourkids."
It is not the first time the bridge has been used to throw rocks at cars below.

In March 2016 four teenage boys were arrested after a number of cars were pelted with stones in the same location.
Speaking at the time PC Chris Bent said: “It goes without saying that throwing stones or items of any kind off a bridge and onto the motorway is an incredibly stupid and dangerous thing to do."
