A MOTORIST is lucky to be alive after a brick thrown by children from a bridge onto the A12 smashed into a van.

Police launched a hunt for a group of children spotted with the brick on the Halstead Bridge near Colchester just after 3pm on Thursday.

The missile smashed through the windscreen of a blue Volkswagen panel van travelling on the southbound carriageway between the Spring Lane and Stanway junctions.

Police say the driver was lucky to walk away unscathed from the smash, which follows a series of similar incidents last year.

The motorist reported seeing the group of children on the footbridge just before the incident to police.

They set up a rolling road block on the A12 to allow officers to search the scene for evidence, but no suspects were found.

Anyone with information should contact DC Steve Clarke at Colchester Police on 101 or call Crimestoppers anonymously on 0800 555111.
