National MP Mark Mitchell says he rushed to Westfield Albany mall to pick up a terrified relative after a masked group robbed a jewellery store in front of families and evening shoppers.
Footage of the robbery shows loud bangs echoing through the mall as a man smashes glass cabinets at the Michael Hill Jeweller store while accomplices dash about collecting stolen goods.
Five men are then caught on a separate camera fleeing into a station wagon parked outside and making their getaway in front of stunned onlookers.
A witness said the incident took place at 7pm in front of "hundreds of people".
Mitchell, a former police officer in the Armed Offenders Squad, said he was at friend's 50th party when he got a "panicked" call from a relative at the mall while the robbery was taking place.
