A group of vigilantes served up some street justice to a Bronx man charged with trying to abduct a young woman on the subway, disturbing new video shows.

The clip, which appears to have been recorded sometime after the early Sunday kidnapping attempt, shows at least three men pummeling and kicking the suspect, Sonny Alloway, who is lying on a sidewalk.

“You’re a f–king rapist, n—a!” one of the men screams.

One man spits in Alloway’s bloodied face after he sputters, “I tried to help her, bro. I didn’t try to rape her.”

The violent video was posted to social media after a first recording allegedly showed Alloway, 48, grabbing the young woman on a 6 train around 2:35 a.m. Sunday and trying to haul her off the train at the Morrison Avenue-Soundview station, police said.

Alloway scurried away to a nearby deli, where he was held by the same group of men until cops came to arrest him, police added. He was taken to a hospital for minor injuries.

The alleged kidnapping victim has not come forward, according to police sources.

Alloway, who lives in Soundview a couple blocks away from the station, was arrested on unlawful imprisonment charges. He was awaiting arraignment in Bronx criminal court Tuesday afternoon.
