Woman robbed at knifepoint on Gold Coast

A 72-year-old woman has been threatened at knifepoint by a pair of teenage car-jackers near a Gold Coast train station.

Police say the pair confronted the woman about 7.40am on Monday near the Varsity Lakes train station before speeding away in her car, heading south on the Gold Coast Highway.

However, they didn't get far, with officers intercepting the vehicle at Coolangatta after it sustained a punctured tyre.

Two Bundamba men, aged 18 and 19, will face Southport Magistrates Court on Monday charged with armed robbery and unlawful use of a motor vehicle.
