Disturbing vision has emerged of the moment a shoplifter goes lashes out with a metal pole at an IGA in Perth’s north.

The woman was spotted on CCTV slipping goods into her bag moments before staff at the Aveley IGA attempt to stop her.

“I think they worked it out, it was $90 alone worth of goods in there,” Aveley IGA co-owner Americo Bereira said.

“I was a bit nervous. I thought she was going to hit me with (the pole).

“That’s why I tried to take the pipe off her and try to calm her down.”

The rampage happened on Friday afternoon in front of terrified shoppers after staff took the woman’s bag to check it.

The woman eventually left the store empty handed.

Police have been notified.
