Two people have been arrested in Canterbury overnight following a string of aggravated robberies during which shots were fired at police.
Police received reports of the first aggravated robbery at Timaru Post and Gift Shop at 4.45pm by a man armed with a knife, Canterbury rural area commander Inspector Dave Gaskin said.
The man was reported to have fled the scene on foot.
A second alleged robbery was reported shortly after 7pm at the BP Petrol Station in Fairlie.
The man's description was similar to that of the first robbery and he was reported to have been carrying a firearm before fleeing the scene in a vehicle, Mr Gaskin said.
"Staff were deployed and cordons set up and as a result the vehicle was located a short time later in Totara Valley near Pleasant Point.
