A young woman who overheard a man bragging to his friends about cheating on his girlfriend has sparked a huge Twitter hunt.
Emily Shepherd was on a Bournemouth to Manchester train at about 5pm on Friday when she overheard "Ben" chatting to his mates.
The Bournemouth University student tweeted: "If anyone has a boyfriend called Ben.... he's just told his friends he's cheating on you."
It has since been retweeted more than 26,000 times.
Even Deborah Meaden, from BBC Two show Dragons' Den, has got involved in the search, posting: “Dear cheating Ben... can you please make yourself known before all the non cheating Bens find out where you live...”
Many people have been supportive of Ms Shepherd's actions, with one Twitter user saying: “I'm glad you've exposed him” and another adding: “We salute you Emily.”
Another said: “We live in a society where we turn a blind eye to things which are bad or wrong on basis it has nothing to do with us.
“Good on you @emilyshepss for exposing a cheat!”
However not everyone has taken kindly to Ms Shepherd’s tweet.
One person said: “Unless he's lying to the friends in an attempt to impress them... best not to get involved in the complicated lives of total strangers...”
Another added: “Have you considered that the lad is just giving it the big one to his mate? Probably has rock bottom self esteem and now you’re snaking him without evidence.”
Ms Shepherd told the BBC: "It's been crazy - I've received so many comments from people supporting me and you get the usual trolls trying to bring you down.
"I've had a few people sending me pictures saying 'does he look like this?', 'what does he look like?' but there's no sign yet."
