Stones thrown from Belstead Bridge above A12 in Suffolk
Three young people seen throwing stones from a bridge on the A12 in Suffolk, which smashed a van's windscreen, are being sought by police.
The youngsters were seen throwing the stones from Belstead Bridge on the southbound A12 on Tuesday afternoon.
Last December rocks were thrown from the same bridge on to a car during a spate of incidents in both Suffolk and Essex.
Suffolk Police said the van driver was not hurt in the incident.
Police are appealing for witnesses.
