Police save woman from sinking with BMW, drag her to safety seconds before she ran out of air after she drove off a pier

A woman whose car drove off a rock wall of a car park into a harbour and immediately began sinking at a frightening speed was reportedly saved by policemen.

The petrified woman was squashed up against the rear window as the front end of the BMW was rapidly submerging into the Waitemata Harbour in Auckland at 3pm on Tuesday.

Fortunately for her, witnesses called emergency services as quick-thinking heroic policemen arrived and sprung straight into action by jumping into the water and managed to shatter the rear window before pulling out the relieved woman.
