The Independent Police Complaints Commission is appealing for information following a road traffic incident in which a man died in Reading on Monday.
A red Ford Fiesta was being pursued by police for failing to stop when it collided with the central reservation of the A33.
Six police vehicles, including one dog van and an armed response vehicle, were involved in the incident.
The Fiesta was travelling along the southbound carriageway of the A33, it then performed a u-turn and was travelling in a northbound direction when the collision occurred at around 11.25pm.
The driver, who was the sole occupant of the car, was thrown into the road and hit by at least one of the pursuing police vehicles.
The driver died at the scene.
A post mortem and formal identification are due to take place later today (Wednesday, 13 February).
