Woman who keyed $104,000 Tesla car in a Sydney mall car park caught on camera

A woman has vandalised a NZ$104,000 Tesla but little did she know she'd be caught in the act with the car's self-surveillance technology.

The footage captured in Sydney's Westfield Penrith mall car park shows the woman lingering beside the car before sliding a key down the side of the vehicle.

Known as "keying", this practice is a common form of vandalism.

The vehicle's owner, Darren Pearce, posted the footage to Facebook. The woman has since been caught and charged by police and will appear in court next month.

"Just got home from Penrith Westfield shopping centre when I realised my car had been keyed. Luckily it was all caught on sentry mode, it shows this lady keying my car clear as day," Pearce wrote on Sunday.

He said the vandalism left a "big white scratch".

"Why? I don't know why?" he told 7 News.

"I'm not going to park there anymore. I just don't want to risk it."

Five years' imprisonment is the maximum penalty for such an offence.
