The disturbing accusations levelled at Catfish's Nev Schulman.

Nev Schulman, the once-adored host of MTV’s Catfish, now has two allegations of misconduct towards women against his name.

After being expelled from the prestigious Sarah Lawrence College in Manhattan, New York, in 2006 for allegedly punching a woman in the face, Schulman has now been accused of sexually harassing a participant on his reality show in 2015.

In two blistering Youtube videos, Ayissha Morgan, who identifies as lesbian, talked of her experience with “Jack” – a moniker for a well-known member of the Catfish team – who she says repeatedly made her feel uncomfortable during breaks in filming.

“He just kept asking me, ‘Are you a lesbian or are you bisexual?’ I was like, ‘I’m a lesbian for the 50th f—king time’,” Morgan said in the video, which has been watched by more than 500,000 people.

From there, she says, the situation escalated.

“[Jack said] I don’t think you’re a lesbian… I don’t think you met the right guy yet,” and, Morgan alleges, proceeded to ask if she found him attractive.

Later, Morgan says the man came into her hotel room and asked her to “cuddle”.

The Catfish contestant also alleged another crew member – given the pseudonym Carol – assaulted her, explaining that after a night drinking together, she woke to find “she was on top of me.”

In a statement to PEOPLE, Schulman denied the allegations.

“The behaviour described in this video did not happen and I’m fortunate that there are a number of former colleagues who were present during this time period who are willing to speak up with the truth,” Schulman said.

“I have always been transparent about my life and would always take responsibility for my actions — but these claims are false.”

Morgan’s allegations come more than a decade after Schulman was booted from his college for physically assaulting another student.

Speaking to Vulture in 2014, the anonymous woman recounted her experience with the father-of-one: “I tapped his shoulder and he turned and hit me out of nowhere, I went down and he held me in a head lock and repeatedly punched me while I tried to get free.

“The impact broke my glasses and the rest of the night was a blur. I got off the floor, talked to police, then went home to sleep. When I woke up the next day, my face was bruised, I was hurt, and a friend urged me to go to the hospital, which I did.”

It was an incident that Schulman addressed in his 2014 book, In Real Life: Love, Lies & Identity in the Digital Age, where he wrote:

While I was photographing, an individual who didn’t like that I was taking pictures attempted to tackle me and smash my camera on the ground. Since the camera was attached to a strap around my neck, I found myself in a very unpleasant situation, much like a dog with a choke collar. In an effort to free myself, I punched the person and ran off; when I returned minutes later, I discovered that the short, stocky, crew-cut-styled individual that I’d fought with was a woman—a fact I hadn’t been aware of in the heat of the moment. The next thing I knew, I’d been arrested.

The woman involved rejected the claims that she ‘tackled’ the now-TV star, telling the publication: “I attended the dance he mentions and saw that he was taking pictures of queer couples dancing and kissing without their permission. I talked to the Student Affairs liaison at the event, who I knew from my work study job, but nothing was done about it.

“I confronted him, and asked him to stop taking pictures. I didn’t tackle him and I certainly didn’t choke him with his camera strap.”

Late last week, MTV announced that production of its flagship show has been halted, while an investigation into the Youtuber’s allegations takes place.

“We take these allegations very seriously,” a spokesperson told PEOPLE.

“We’re working with Critical Content, our third-party production company, to conduct a thorough investigation and we’ve put a pause on shooting until the investigation is completed.”
