A New York college student has been arrested after she allegedly choked a nightclub bouncer unconscious because she thought he grabbed her buttocks.

Kierah Lagrave, 22, was arrested on Thursday and charged with second-degree strangulation - a felony.

If convicted, she could face up to seven years in prison.

Lagrave, who weighs 125lb, was captured on surveillance footage walking up behind a bouncer - believed to be approximately 175lb - and choking him at the Five1Eight nightclub in Plattsburgh around 10.20pm on October 20.

The video, released exclusively to DailyMail.com by the Plattsburgh Police Department, shows Lagrave and a female friend standing by the bar.

A bouncer walks toward by Lagrave's right side as the female friend appears to lean toward her left side.

Lagrave then swiftly turns around and follows the bouncer, wrapping her arms around his neck in a chokehold.

She keeps her arms there until he loses consciousness and they both fall to the floor.

Lagrave told DailyMail.com that the night had started out like any other with her friends.

'We were in the club, minding our own business and having fun,' she said. 'And then I feel a full-on grab on my right side butt cheek.'

'My friends weren't on my right side, so I was concerned. I didn't know if he was going to slip something in my drink. I wasn't going to take any chance.'

'My goal was not to hurt him,' she added. 'But to ensure my own safety.'

'I go out in this town frequently and I have never had an issue before. I wasn't looking for trouble.'

Lagrave said she received a call from police two days later and went to the police station voluntarily.

'When I was giving my statement, the officer would keep saying things like "He didn't do it", "you're wrong", "sooner or later you will have to pay for this,"' she said.

The police decided to arrest Lagrave, saying that surveillance footage 'clearly shows that Lagrave's friend slapped her on the buttocks', City Police Chief Levi Ritter told the Press-Republican.

But Lagrave saw the footage and said it was 'clear that the bouncer was on my right side where I was grabbed'.

'If my friend hit me, she would have hit my left side. Not grabbed my right,' she added.

'She is positive that she didn't do it. She would have told me she did it and stopped everything from taking place.'

Lagrave said she 'was definitely expecting' the charges.

'People in this town have this mindset that men can do no wrong,' she said. 'The police were just trying to shame me. They never once listened to me.'

Lagrave was arraigned in Plattsburgh City Court and released on her own recognizance.

She then wrapped her arms around his neck and choked him until he lost consciousness and fell to the floor, according to City Police Chief Levi Ritter
