A MAN who threw a hamster against a wall and stamped on it to kill it has appeared on ITV1’s The Jeremy Kyle Show today (Wednesday).

Jemma Tracey wants to warn other women off Ryan O'Brien

Ryan O’Brien, of Wisden Road in Stevenage, was sentenced last month after earlier pleading guilty to causing unnecessary suffering to an animal during a drink-fuelled argument with his ex-girlfriend Jemma Tracey.

Unemployed O’Brien, 22, killed Dave the hamster, which belonged to Miss Tracey, after their four-year relationship ended.

O’Brien had found out through a DNA test that he was not the father of Miss Tracey’s 13-month-old daughter, Honesty.

He was sentenced to 24 weeks in jail, suspended for two years, told to attend a substance abuse programme and ordered to carry out 140 hours unpaid work in the community.

Ryan O'Brien admits 'complete rage' in hamster attack

On the Jeremy Kyle chat show this morning, O’Brien said he wished he had been sent to prison after receiving death threats.

“We were having an argument and I didn’t want to hit Jemma,” he said.

“In a blind rage I threw the hamster at the wall. I saw it was on the floor still alive, so I stamped on it to put it out of it’s misery.”

Asked why he killed the hamster, he said: “It was a blind rage. I was quite drunk. If there’s anything I regret in my life, it was doing that. It was just anger. Complete rage. The red curtain came down and I just blacked out. For those 10 minutes of my life I don’t know what happened.”

Speaking about the DNA test, O’Brien said: “For 13 months I believed I was a dad and it broke my heart when I found out.”

Miss Tracey, 23, said she had wanted to appear on The Jeremy Kyle Show to warn other women off O’Brien.

“I want people to know what you have done to me,” she told him. “You made my life a living hell.”

But the show revealed that during their relationship Miss Tracey had been arrested after beating O’Brien in front of police officers and had been convicted of stealing property from O’Brien’s mother, causing his family to turn away from him.

“That’s also vile behaviour by anybody’s standards,” Jeremy said.

“You also conned him into believing he was the dad of a baby that wasn’t his.”

He added: “That doesn’t condone what [he] did.”

Addressing O’Brien, Jeremy said: “I’m glad you are getting every bit of grief, because you deserve it. You should be incarcerated.”

Miss Tracey concluded: “We are as bad as each other and I wish we had never met.”
