He said he felt anxious for the victim, who reportedly suffered lacerations to her face, adding: "It's something that can nearly be traumatising, honestly".
A video posted to Twitter shows a blond woman repeatedly spitting the F-word at a woman next to her who was just minding her own business and looking at her phone.
On Tuesday, 40-year-old Anna Lushchinskaya boarded a New York City subway train.
Juan Ayala, who filmed the incident, eventually made a citizen's arrest after she turned on him, and held Lushchinskaya until police arrived to take her into custody.
Numerous videos captured the woman, who is white, kicking a woman, who appears to be Asian, and using an umbrella and keys to hit her.
While someone tried to grab the umbrella from her, telling her, "You're going to make us all late for work, bitch", Lushchinskaya continued to attack the woman, and even called her a "fucking c**nk".
The maniacal, blonde-haired woman is then seen taking off her sunglasses, putting her hair up in a ponytail, and pulling an umbrella out of her bag.More news: Nissan sues Ghosn's sister while Renault finds no irregularities in his pay

In the second clip below, the action picks up where the first clip leaves off. Lushchinskaya makes a few more attempts to hit the 2nd woman and then makes a phone call, apparently dialing 911.
The NYPD announced on Twitter Thursday morning confirming Lushchinskaya's arrest, thanking those who provided information and assistance leading to her capture.
A woman was raped by a stranger after falling asleep on a subway train in Brooklyn, police said. World Star Hip Hop is the name of a website known for posting videos of viral beatdowns.
Passengers on the train shout at Lushchinkskaya and appear to try to block her attack. In that arrest, she also picked up assault charges. "I just had a bacon egg and cheese yesterday".
"We gotta detain her until the cops come".
"Bystanders worked to separate the two women; however, things escalated again when Lushchinskaya, who is white, called the other woman, who is of Asian descent, a "f"**king c***k".
According to a statement sent to Yahoo Lifestyle from the New York City Police Department, the 24-year-old female victim said the brawl started when Lushchinskaya bumped into her. "It's not a situation that anybody should be involved in, especially a little girl", he said.
