According to police, the 64-year-old victim was riding on an S40 MTA bus around 9:10 p.m. on August 13.
When the bus stopped at the intersection of Clinton Avenue and Richmond Terrace, the suspect stood up behind the victim and reached into his shirt pocket.
Video of the incident shows the victim grabbed the suspect, and as the two struggled, cash spilled out onto the floor.
The suspect grabbed two handfuls of the cash and ran off the bus.
He was wearing a mask at the time, but police released more video showing the suspect inside a store and a clear view of his face.
Police are hoping someone recognizes the man and calls the NYPD's Crime Stoppers Hotline at 1-800-577-TIPS (8477).
