The chase for Jake Dohnt began when he failed to stop for police and then later allegedly pointed a handgun at officers in Wallaroo early on Monday.

His car was eventually road spiked north of Port Wakefield on Tuesday evening.

The 25-year-old was arrested at gunpoint after fleeing his car when it collided with another car at the intersection of the Copper Coast and Port Augusta highways.

Dohnt will appear in the Port Pirie Magistrates Court today charged with endanger life, driving dangerously to escape police, aggravated assault and firearms offences.

Also arrested on Tuesday in relation to the Wallaroo incident was a 27-year-old Adelaide woman who was charged with impeding an investigation and breaching bail.

She was refused police bail and was expected to appear in the Adelaide Magistrates Court today.

Police searched houses and other properties in the Wallaroo area on Tuesday and found a firearm in the backyard of one property which was sent for forensic testing.
