A viral Facebook post shows two women eating dinner when a thief enters the restaurant on a bike and snatches one woman's purse without even losing momentum.

KITV4 spoke with the victim who says her friend was recording the dinner for a restaurant review of Pioneer Saloon on her YouTube channel.

The victim and Honolulu Police Department echo the importance of remaining vigilant in public locations.

"Just be aware of where your belongings are," said Chris Kim of HPD.
