A Brownsville man is facing charges in connection to a pit bull attack on the subway that was captured on video.

Ruben Roncallo,53, was arrested Thursday, police say. He is being charged with assault and reckless endangerment.

The incident happened on April 20 on a Manhattan-bound 4 train.

According to police, the woman asked Roncallo to move his dog when it bumped her seat, then she pushed the dog several times until Roncallo hit her.

Witnesses say the dog bit the woman and latched onto her leg once she hit Roncallo back.

A friend of Roncallo says the dog, known as Vinchy, is a very loving and playful pit bull and a service dog.

According to the MTA's rules, nonservice animals need to be in carriers while on mass transit.

Vinchy is registered as a service animal, however, officials did not specify what service he is being used for.

The dog and owner will remain together because Vinchy is classified as a service animal, officials say.

Roncallo was arraigned and released without bail Friday.

He will be back in court May 15.
