Despite staff feeling unsettled, the shop had re-opened and staff were trying to get on as normal on Wednesday afternoon.
Security measures, such as a fog cannon and alarms, did not come in handy as the store had been opened and alarms disarmed, the staff member explained.
A nearby shop worker said it was sad for the staff involved and unsettling for people working in the industry.
“It’s understood a group of people have arrived at the premises in a stolen vehicle, verbally threatened a staff member, before taking some items and then left the area in a second vehicle, which is also believed to have been stolen,” a police spokesperson said.
“The person who was in the premises at the time is being provided with support by police and thankfully no injuries were reported.”
Both vehicles have since been recovered for forensic inquiries and attempts are being made to locate those believed to be involved.
