A woman and young child were carjacked in Manurewa by two armed men who had just robbed a sports bar and forced the woman to drive them away from the crime scene.
Police said two men entered the Sports Bar on Great South Road near the Southmall shopping complex on Monday morning.
One of the men stood at the entrance holding a weapon and stopped patrons from leaving. The second offender went behind the bar area and stole the till.
Both offenders ran from the Sports Bar through Southmall and across the overbridge of the Manurewa Train Station.
"After they fled the shopping complex, the two offenders forced a member of the public to stop her car," said Detective Senior Sergeant Ross Ellwood.
