Gardai have warned a motorist could be killed after a number of missiles were thrown at vehicles from bridges overlooking Irish motorways recently.
In one case, a rock is believed to have been flung from the M8 flyover outside of Cahir in Tipperary and hit a passing car undeath causing damage to the windscreen.
The driver, who was left shaken, had noticed a group of people on the bridge and was able to slow down before the incident.
