Women robbed at gunpoint after taking pic

A Brisbane woman has been robbed at gunpoint after taking a photo of a suspicious-looking couple on her mobile phone.

Police say she was in the carpark of a Mount Gravatt sports club on Tuesday afternoon when she saw a man and woman acting suspiciously.

After snapping their photo, the man threatened her with a hand gun and stole her phone.

The pair then fled in a sedan, which was later found abandoned.
