Police are once again crediting Kaitaia's Building Safer Communities CCTV network with thwarting a "probable" attempt to rob a service station.
The service station attendant was advised to lock the doors after the camera monitor, at the police station, saw three Auckland men acting suspiciously at 9.30 on Thursday night.
At one point they tried to pump petrol into their car, but left when they discovered the bowser was set for pre-pay.
Eventually one of the trio took a $5 bag of mandarins and they left.
Police found the car in Kaitaia a short time later, and seized what was described as a mini Samurai sword that was under the passenger's seat. The thief returned to the service station to pay for the mandarins.
