Marc Gomez, 36, was arrested after he was captured on camera repeatedly kicking a woman on a New York Subway. He now claims she threatened him with a knife

The fiancée of the man who was caught on camera viciously attacking an elderly woman on a New York subway train claims she had threatened to kill them.

Asia, who did not give her last name, said she was riding the subway with Marc Gomez and her 11-year-old daughter when the 78-year-old woman began yelling at them.

She claims the woman screamed 'I'll stab you and your wife and your child!' at them.

'She kept going off about stabbing and killing people,' Asia told the New York Post.

When the family got up to get off at the stop, Asia claims the woman screamed 'I'll kill you, I'll kill your wife, I'll kill your daughter!'

'Again, she yelled "I'll kill your daughter" and she had something in her hand,' Asia said.

'She shifted towards us and the door and [Gomez] lost it. He just started kicking her.'

Gomez, 36, was charged with felony assault after the video was posted to Twitter and quickly went viral.

Nearly 13 million people have watched video of the vicious attack, which was posted on Twitter this week and prompted outrage both for its brutality and for the fact that bystanders on the train filmed the incident instead of trying to help the woman.

The video shows Gomez attacking the elderly woman at the Nereid Ave Station in the Bronx around 3.10am on March 10.

Gomez can be heard saying 'Who the f**k you was talking to' as he repeatedly kicks her head and body while wearing boots.

Prosecutor Theresa Genthe said Gomez 'viciously kicked' the woman six times.

Before he leaves the train, Gomez tells two people who are filming him to 'Worldstar that my n****r'.

The quote is in reference to WorldStarHipHop.com, a website known for its violent videos.

He then got off at the 238th Street/Nereid Avenue stop and fled on foot. The woman was left in her seat cradling her head in her hands.

Police weren't notified until the train arrived at the next and last stop, at Wakefield-241st Street station, when a bystander approached an officer in the station.

The woman exited at 241st Street station, where she was met by first responders. She suffered bleeding and swelling with cuts to the face.

Asia said Gomez was a 'good man' and that nobody had recorded the incident 'from the beginning'. She said her fiancé also felt 'really bad' afterwards.

'I could see it in his face after it, he was upset,' she said. 'It wasn't like he intentionally went after her.'

Gomez, who was arrested on Saturday and charged with felony assault, has also claimed that that elderly woman threatened him with a knife.

'She was homeless and lying across the seat and wanted all other passengers to move,' his lawyer said during the arraignment on Sunday morning.

'She said, at that point, "I have a knife and I'm going to stab you" and flashed a sharp instrument.'

A former neighbor of the woman told the New York Post that she is mentally ill and has threatened others with a knife in the past.

They said she is a retired kindergarten teacher who had moved out of the residence three or four years ago.

'She was just mentally ill,' they said. 'She wasn't paying rent. She threatened at least three co-opers with a knife. She used to call the fire department, cops, all the time.'

Asia said she and Gomez hope that the woman 'gets all the mental health she needs'.

The video was first posted on Twitter by a user named @BKLYNRELL1. The caption read: 'He's crazy that's somebody grandmother. Rt and find this a*****e.'

'For everybody asking me if this is my video. No and if I was there it was not going down like that. He was not getting away,' he later added in a separate tweet.

NYPD Chief Dermot Shea announced on Saturday that Gomez had been apprehended and was in police custody.

Shea said the woman was treated in a hospital for her injuries and was 'getting the care, advocacy, and support needed'. She has since been released.

A tipster who had seen the viral video recognized Gomez and reported him to police.

He has also been previously arrested for assault and possession of a gun and marijuana.
