A man has been arrested on suspicion of dangerous driving and robbery after an incident in Carlisle.
Police say a black Audi was involved in a crash, but failed to stop, at around 7:30pm on Warwick Road.
The car was then chased through the city by officers, resulting in a collision between a police vehicle on Victoria Viaduct.
The 36-year-old remains in police custody.
A witness appeal has been issued for both incidents and anyone with information or dashcam footage are asked to contact 101.
