Warwickshire Police are appealing for witnesses after a road collision on the A425 near Southam.
The incident happened at Ufton Hill, Ufton, last Friday (May 22) at about 3.50pm.
A red Daihatsu was travelling up the ill and a police vehicle was driving in the opposite direction with its blue lights and sirens on.
As a result, the Daihatsu pulled suddenly into the end of a driveway which is believed to have caused a collision between two other vehicles and a motorcycle.
Nobody was injured.
The Daihatsu then drove off from the scene without leaving any details.
Police are eager to trace the driver of the Daihatsu.
They may not have realised a collision occurred behind them, but officers would like to speak with them.
