Yobs who throw stones off bridges onto cars for fun have been warned by police they could kill motorists and face significant jail time.
In recent years, a number of main roads in Northamptonshire have suffered problems with youths throwing stones from bridges.
Police said today that just last week two vehicles had their windows smashed after large stones were thrown at them as they travelled along the A45 near the Riverside Retail Park.
It follows the death of a lorry driver in 2008 after a teenager pushed a breezeblock off a bridge over the A45. The lorry driver died instantly and the youth pleaded guilty to manslaughter.
Police said dual carriageways, especially the A45, are partucular problem areas.
Chief Inspector Dave Lawson said: “Following the death of a lorry driver in 2008, you would think this kind of behaviour would have come to an end.
“Sadly that is not the case and some people continue to endanger the lives of motorists by throwing items from bridges in the county.
“But they need to know that they don’t just run the risk of killing innocent drivers, they also risk ruining their own lives by ending up in prison.
“Both youngsters and their parents need to get the message that we will not tolerate this kind of behaviour and those who continue to break the law by throwing objects from the county’s bridges will be taken to court and face substantial charges.”
When the force receives reports of objects being thrown from bridges onto roads, officers are immediately dispatched to the scene to catch the culprits.
Anyone who has any information about people who throw objects from bridges can call Northamptonshire Police on 101. Alternatively, information can be given anonymously to Crimestoppers on 0800 555111.
