Cheating within relationships is a sad fact of life that people, unfortunately, have to accept. It’s all too common for a person to sleep with someone else while they are in a supposedly monogamous relationship, and, in some instances, brag about their behavior.

However, when a man named Ben bragged about this infidelity, the last thing he expected was to become the subject of an online witch hunt.

That’s why cheaters should think twice before openly discussing their scandalous indiscretions in public places. Unless, of course, they want anyone within earshot to expose them on Twitter for being the lying cheat that they are.

That’s exactly what happened when 23-year-old Emily Shepherd, pictured below, overheard a man named Ben bragging to his friends about being unfaithful to his girlfriend. She immediately put herself in his girlfriend’s shoes and decided to take action.

Emily and the shameless philanderer were on a train from Bournemouth to Manchester, England. But Ben could never have guessed that Emily, a perfect stranger, would use her Twitter account to reach out to his unsuspecting girlfriend and tell her to “dump his ass”.

The post has currently been retweeted 26,000 times in an attempt to identify the cheater who divulged all the dirty details to his pals on the train.

“If anyone has a boyfriend called Ben on the Bournemouth – Manchester train right now, he’s just told his friends he’s cheating on you. Dump his ass x” Emily wrote on Twitter.

Emily posted the Tweet early last Friday and, while the cheater has yet to be revealed, there is hope yet as the hunt continues to rage on.

“For those asking: Ben is yet to be found, I’ve had several messages but nothing yet,” Emily later tweeted. “I’m now on the Manchester – Bournemouth train and no sign yet… thanks to everyone calling me a grass and a snake, you’re all great.”

But little did Emily know that the hunt Cheating Ben was about to intensify when celebrities got involved…
