Stun grenades have been used by police in a dramatic end to a car chase in Adelaide.

The chase started just before 6:00pm (ACDT) on William Street at Norwood on Monday when police attempted to check "the welfare of a driver" but the man took off in an "erratic" fashion.

Police said they pursued the 44-year-old man, from Salisbury East, using a patrol car to stop traffic at a roundabout, but the man drove into the police car before driving away.

No-one was injured in the collision.

STAR group officers then used "tactical options", which included using sound and flash grenades to stop the car at Railway Terrace, in Mile End.

The man received minor injuries during the pursuit and was taken to the Royal Adelaide Hospital for treatment and a mental health assessment.

He was later charged with engaging in a police pursuit, driving in a dangerous manner and at a dangerous speed, acts to endanger life and aggravated driving without due care.

The man is expected to appear before court in a bedside hearing today.
