THREE teenagers have been quizzed over an incident in which rocks were thrown at vehicles on the A14, police revealed today.

The youngsters were questioned by officers in connection with an attack on vehicles on December 15 when missiles were hurled from a flyover in Trimley St Mary.

Five vehicles – including an ambulance on its way to a call-out, an articulated lorry and three cars – had windscreens and wing mirrors smashed.

The attack is thought to have been carried out by a group of eight to 12 youngsters during a 20-minute period.

A police spokeswoman said three boys aged 14 and 15 had been identified and spoken to following the incident. No arrests have been made and investigations are continuing.

Police are following up a number of leads and expect to talk to other youngsters, too.

The spokeswoman appealed for anyone with information about the incident – and other attacks – to come forward.

“Someone must have some knowledge of those involved and we would like people to come forward with information before we are looking at a very serious incident,” she said.

There have been a number of similar attacks on cars on the dual carriageway at Trimley St Mary, near the Shell garage close to the Orwell Bridge, and at Haughley. The most recent incident took place on Tuesday night near to the A142 junction on the Suffolk-Cambridgeshire border.

There was also an incident on the A12 at Belstead. In the worst incident, a woman was seriously injured after a large lump of concrete was dropped through her windscreen on the A12.

Police do not believe the incidents are linked and feel they are copycat attacks. Patrols have been stepped up on the dual carriageways in a bid to catch the culprits.
