A spokesman for Lancashire Police said officers were responding to a report of a domestic incident in Whitworth, Lancashire, when they noticed a Sprinter van 'driving erratically'.
"We requested it to stop. It failed to stop and a pursuit developed which ended a short time later when the Sprinter van rammed the police car and made off," he said.
A female officer suffered minor injuries in the crash, the spokesman confirmed.
The M.E.N. has asked GMP for a comment.
