West Palm Beach, FL (WPTV/CNN) - A 19-year-old Florida man is being held on a $25,000 bond for allegedly attacking and robbing two elderly sisters.

Adam Bardisa made his first court appearance Tuesday.

Police say the teen rode his razor scooter into a Publix supermarket behind the victims.

Then, he allegedly followed the 84 and 96-year-old women to a bus stop.

A police report says Bardisa knocked the ladies over, and took their money.

One of the women broke two ribs.

The teen's father turned him in to police after spotting him in crime scene surveillance photos shown on the news.
