YOBS who throw rocks at cars on a busy Ipswich road could cause a fatal accident, police warned today.

The force is stepping up patrols in and around London Road after a number of vehicles were damaged when missiles were hurled at them.

But police are more worried that a driver will be seriously hurt or even killed attempting to swerve the rocks.

The warning comes just a few weeks after a motorist using the A12 in Essex had to be treated in hospital after concrete was thrown at his vehicle from a bridge near Chelmsford.

A Suffolk police spokesman confirmed: “There is a real concern that something more serious could escalate. It's pure stupidity.”

The gang responsible began their dangerous campaign on Tuesday evening and continued the following night.

The rocks were thrown between 9.25pm and 9.50pm on the section of London Road which runs between Chantry Park and the Chantry estate.

Eight cars suffered damage - ranging from scratched paintwork to smashed windows.

Police despatched the force helicopter and police dogs to the scene after the first incident was reported but officers were unable to find the culprits.

Meetings have been held among the area's Safer Neighbourhood Team to discuss measures to prevent a repeat of the trouble.

Police are also increasing patrols and will deploy plain-clothed officers in a bid to find a breakthrough.

The spokesman added: “We will be monitoring the situation on a daily basis and maximising any forensic opportunities.”

Anyone with information should call Pc Stephen Bright at the South West Ipswich Safer Neighbourhood Team on 01473 613500 or Crimestoppers on 0800 555111.
