He said one of the people who entered the store had a knife in hand.
The perpetrators made it out of the store with the till, which contained an estimated $1000 to $1200 in cash, and staff were still checking stock to see how much had been taken.
A police spokesman said police responded to a robbery at a petrol station on Hyderbad Rd, around 3.30am.
“Two vehicles were involved, and the offenders smashed the glass to gain entry. The offenders were armed with weapons (not firearms), various items including the cash register were stolen,” the police spokesman said in a statement.
He said police inquiries were ongoing to identify and locate those responsible.
“We understand this would have been a distressing incident for those involved, and we are in contact with the victims, who have been referred to Victim support,” he said.
There were no injuries reported.
