Two men on a motorcycle came alongside the woman as she rode along the road behind Jungceylon shopping mall in Patong about 12.30am.
The man on the back of the motorcycle attempted to steal a shoulder bag the woman was carrying. In trying to grab the shoulderbag, the woman toppled from her motorcycle.
The would-be thieves rode off. A woman who saw the incident, a Phuketwan reader, took the photo.
She said the victim was dazed, but pleased to have kept her bag. As a witness, she said the incident convinced her that she should look for work in a safer place.
Phuketwan was not able to get an answer from Patong police to ask whether the crime was reported.
