Late last night a Taradale service station was robbed by two men wielding knifes and demanding cash.
At about 11.10pm two offenders wearing red bandannas entered the Z garage on Lee Rd, Taradale, a police spokeswoman said.
The female shop attendant had opened the doors to allow a customer in to purchase cigarettes.
After the customer left and before the shop assistant could lock the doors, two male Maori entered the store and confronted the woman with knives, demanding cash and cigarettes.
The offenders fled down a service alley behind the garage with cash and three packets of cigarettes.
A police dog tracked the offenders for a short distance behind the shops where it is believed the offenders had a vehicle waiting.
