Two police officers have been slashed with a boxcutter while attempting to arrest a teenage driver north of Adelaide.

Police will allege that the 17-year-old Ferryden Park man was driving a stolen grey Honda CRV in the backstreets of Mansfield Park just after 9.30am on Tuesday.

He was seen heading north on the Salisbury Highway.

The police helicopter tracked the car north on Port Wakefield Rd where it stopped near Wild Horse Plains.

A patrol approached the car and the youth threatened the two officers with a boxcutter.

A female officer was slashed to her fingers and the male officer received an upper arm injury.

Both police officers were treated at the scene by paramedics.

The teenager was arrested and taken to Elizabeth Police Station for charging.

He is expected to be charged with offences relating to a stolen vehicle as well as aggravated assault against the two officers.

The car has been removed for forensic testing and was stolen during a break-in at Ferryden Park on Monday morning.

Anyone who witnessed the incident, particularly the driver of a white van who may have been approached by the teenager, is asked to contact Crime Stoppers on 1800 333 000 or by going online.
