NEW YORK (CBSNewYork) — Police say they are looking for two suspects after a subway rider was dragged and beaten during a robbery in the Bronx.

The incident, which was caught on surveillance video, happened around 4:40 a.m. Monday at the Pelham Parkway/White Plains Road station.

Police said it all started when a woman seen on the video asked a 61-year-old man for money. When the man walked past her and continued up the stairs, police said another man followed the victim and then punched him in the face and dragged him down the stairs.

That’s when police said both suspects began punching the victim, trying to take his bag. Eventually, a passerby intervened and police said the two fled with $20 the man took from the victim’s pocket.

“Very sad. There’s no respect anymore,” one resident said. “Need more cameras, more cops.”

“Just for $20, it’s really not worth it,” said another.

The victim’s son said his dad is OK but was taken to Bronx Lebanon Hospital with bruises and given a neck brace.

“I tried to protect myself,” he told CBS2’s Scott Rapoport. “He tried to rob me… I tried to fight him off.”
