The victim attempted to take out her cell phone to photograph the suspect as he was riding away, but in the process of doing so, she fell and injured her hand.

The suspect was described as a tall male in his thirties with a medium build, possibly with light brown hair. He was wearing a light orange short-sleeved T-shirt and shorts that were either dark blue or dark gray.

As the victim never saw the suspect’s face as he rode by, no suspect sketch will be forthcoming.
