UPDATE: Two armed men who held-up a Bunnings hardware store in South Perth this morning escaped in a stolen vehicle.
The men entered the store about 7.20am, with one believed to be armed with a firearm and the other man with a knife, police said.
The store, which opens at 7am, had customers in the store at the time of the hold-up.
Police confirmed the vehicle the offenders fled in was stolen from Secret Harbour overnight.
"All our team members and customers are safe," a Bunnings spokesman said.
A sign outside the store told customers that "due to an incident" the store would be closed until noon.
Bunnings staff turned away several customers as they tried to enter the store after the incident.
South Perth residents Ron and Caroline Doig were shocked to hear about the hold-up.
"They just told us it was closed due to an incident, so we assumed it might have been something internal – between staff," Mrs Doig said.
"We would never have thought it was an armed robbery."
Mr Doig questioned the motives of anybody who would try and rob a hardware store.
"How idiotic are these people to rob a hardware store," he said.
Police described one of the men as white, 183cm tall, slim to medium build, wearing a green army jacket, blue jeans and a balaclava.
The second offender was described as a 175cm-tall male.
The men left in a white Toyota four-wheel-drive camper van with a shell on the back, registration 9IU 140.
The car was last seen travelling towards Burswood on Canning Highway.
