Horrified clubbers looked on as a man reportedly dropped his trousers and defecated on the dance floor of a Maidstone club this weekend.
Police were called to The Source Bar, in Rose Yard, at around 1am on Sunday to reports of a man needing assistance.
According to revellers, he relieved himself on the dance floor a couple of metres away from the toilets.
He was passed on to volunteers at the Urban Blue Bus, who cleaned him up before arranging for him to be collected.
Now founder Paul Alcock is warning clubbers about the effects of drinking laxative drinks on nights out.
He said: "We tidied the guy up and got him home. He was totally out of it - I don't think he knew what he was doing.
"The problem is people are drinking laxatives like Red Bull and don't realise what they are. This is not the first time we have had to deal with something like this.
"It is one of the unfortunate things our volunteers have to deal with."
Around a month ago, the Urban Blue Bus looked after a woman who had soiled herself while partying in The Gallery in Bank Street.
The man was not charged by police, but further action may be taken.
