POLICE said motorists could have been killed after thugs bombarded rush hour traffic from a bridge over the M8.
The roof and windscreen of at least two vehicles were badly damaged after heavy objects were dropped from a bridge over the motorway in West Lothian.
The hunt follows two horrific incidents in England where concrete blocks were hurled on to a motorway from an overpass, in one case causing serious injuries.
Lothian and Borders Police are now appealing for witnesses after incidents on Saturday evening and last night (Monday).
On Saturday night (December 3) a car was struck by a large object as it passed under the B792 Blackburn to Bathgate bridge about 7.50pm.
No one was injured in the incident, but the roof of the vehicle was significantly damaged.
Last night, during rush hour traffic, a van’s windscreen was smashed by an object which was thrown from a footbridge.
The attack happened near Blackburn at 7.10pm, and again there were no injuries.
A police spokeswoman said officers were not able to locate the objects as they searched around the areas after the incidents.
And the drivers of the vehicles were not able to see exactly what hit them.
Inspector Simon Bradshaw said: “We are appealing for anyone who may have been in the area at the time, and who may have seen what happened, to contact police on 0131 311 3131.
“Fortunately in both incidents no one was injured, but there is every chance that this mindless vandalism could have had far more serious consequences.
“By compromising the vision of one driver, the lives of everyone on that road are put in danger.
“The M8 is Scotland’s busiest motorway, so these incidents could potentially have caused multiple fatalities.”
Anyone with any information should contact Lothian and Borders Police on 0131 311 3131, or the charity Crimestoppers in confidence and complete anonymity on 0800 555 111.
Police in Essex are conducting an attempted murder enquiry after two ‘bucket sized’ chunks of concrete were hurled onto a motorway last week.
A woman was left with life-threatening injuries after the block came smashing through her windscreen, and another woman and her daughter escaped with a shaking in an earlier incident.
The attacks happened about eight miles apart.
