According to police, a woman wearing medical scrubs punched a 67-year-old woman in the chest and then choked her briefly. She also is accused of bending the victim’s finger back during the incident.

Police say the attack happened in the back of the bus, and the cameras in the front of the bus probably didn’t capture the incident.

The suspect got off the bus and ran into the 86th Street R subway station, where she was caught on surveillance video.

“The area is changing. Not for the better I’m sorry to say. You just have to be careful,” said Bay Ridge resident Ellen Petropole.

“You look at people as like a mother figure. Anyone who would do anything to harm anyone, especially that young, you have no kind of respect,” said Megan Clarke of Queens.

CBS2’s Aundrea Clark-Thomas spoke to the victim’s family, who said she’s out of town. Her injuries didn’t require medical attention, they said.

“It’s a bad situation. I hope she feels better. I hope something happens. Stuff has to get better around here,” said MTA rider Andrew Ubanwa.
