During the early hours of this morning, police noticed a vehicle driving dangerously in the Thornaby area.
Officers from the Road Policing Unit and the Dog Unit pursued the vehicle and attempted to stop it with a stinger (device to enforce a controlled stop) on Elizabeth Street.
The vehicle continued to drive at speed towards an officer who was then hit and thrown across the floor which resulted in him being injured.
Two men were arrested following the incident.
A man, 31, was arrested on suspicion of assault, dangerous driving, drink driving and failing to stop.
A 32-year-old man who was the passenger in the vehicle was arrested on suspicion of assault and for resisting arrest. Both men remain in custody.
The injured officer was taken to hospital where he was treated for minor injuries to his hip and cuts and bruises and was later released.
As a result of the pursuit it was also reported that a police vehicle had collided with a taxi on Langley Avenue.
This has been dealt with and no one was injured as a result of this collision.
Enquiries are ongoing.
