A man was caught on video last week abusing his two young sons in a Bronx subway station — and police said Thursday he’s now the focus of an NYPD probe.

The clip shows a 35-year-old man sitting between his two sons, 7 and 9, on a bench at the Fordham Road/Jerome Avenue subway station around 9 p.m. Friday. He yells at both children — punching one twice and grabbing and shaking the other around by the hair. 

Community advocate Tony Herbert posted the disturbing video to Facebook Wednesday, and said in a later post that the man who initially filmed it — who was on his way to pick up his own son from chemotherapy treatment — filed a report with the police.

Police are investigating an “open complaint” about the dad, who has a history of domestic violence incidents involving his kids, authorities said Thursday.

The man had not been charged as of late Thursday morning.

Police confirmed the same man was arrested Saturday for allegedly being “physical with his family” — and subsequently released. 

The children were in their mother’s custody as of Thursday, according to cops. 

“I am in tears and feeling all levels of anger watching this video where this guy is terrorizing these kids and hurting them,” Herbert said Wednesday, according to ABC 7. “I am a father of three boys, and seeing this abuse screams we need to help and protect them.”

In a statement, the Administration for Children’s Services said that it was investigating the case with the NYPD.

“Our top priority is protecting the safety and wellbeing of all children in New York City,” a spokeswoman said.
