An Auckland petrol station owner and his wife successfully warded off what they say was a would-be burglary on Monday night, by setting off a fog cannon to deter the attackers, NZ Herald reports. Zahid Chaudhry was at work at the g.a.s petrol station in Swanson and was preparing to close the station, when three cars carrying a large number of youths pulled up. Chaudhry ran inside and closed the cage, while his wife pushed a panic button and another button for a fog cannon, releasing a stream of fog at the front door as the youths started to come inside. Chaudhry and his wife were not injured, and there was no damage to the shop.
