A police car was rammed as thieves tried to steal a JCB from a college in Birmingham last night.
A gang broke into the compound of the National Construction College in Kings Norton and used the JCB digger to force open the gates.
The thieves were spotted by a passing patrol car less than a mile away.
The gang rammed the patrol car, damaging both vehicles, before jumping into a Land Rover Defender that had been running in convoy.
Both police officers were uninjured.
