Police in mid-Canterbury are still looking for a man who sparked an armed offenders squad callout on Tuesday.
The man was pursued because he was believed to have stolen a car, police say, and when stopped the driver swung some sort of weapon at a constable.
The car was then abandoned by the Rangitata River.
A seach by armed offenders squad officers and dogs failed to find the man
Ashburton police now say they believe the man may have stolen another car from the Rangitata area and want people to report any unusual activity.
