Man gropes woman. Woman chases him down, makes him pay: ‘I felt the rage coming from my stomach’

One woman took matters into her own hands and refused to let a male passerby grope her without suffering repercussions, WCBS-TV reported.

What are the details?

Chantal Castanon, 26, is featured in a viral video as she angrily chases a man — who'd grabbed her buttocks just seconds before — through a New York City subway terminal on Aug. 31.

Castanon said that she simply reacted when the unidentified man passed by her and groped her backside. She ended up chasing the unidentified perpetrator through the terminal. When she caught up to him, she began hitting him repeatedly.

"It just happened so fast, and when I saw [the video] I said, 'Wow, I can't believe I actually did that,'" she explained. "I didn't even think about it!"

Castanon said that she couldn't help herself — she was so angry that a man would be as daring as to grope a stranger in such a public place that she just couldn't hold herself back and reacted immediately.

"I felt the rage coming from my stomach," she admitted. "I was like 'What did he just do to me? Did he really touch me like that?'"

Castanon added, "[H]e didn't even care; just walked off like it was nothing."

It wasn't "nothing" to Castanon, who gave chase and hit the unidentified man several times, wherever she could land a blow.

"I was just like, 'You know what? You're not touching me like that and getting away with it,'" Castanon said.

What else?

She revealed that the man began apologizing for his rude behavior, but his pleas for forgiveness did nothing to diffuse her anger.

The man was eventually able to free himself from Castanon's furious response, and flee on foot, but Castanon hopes that he's caught.

"I just want him caught, because you don't know who he did it to or who he'll potentially do it to, and it has to be stopped," she explained.
