The Wanted received a ticking off from police after drenching a poet in champagne from their hotel balcony and allegedly verbally abusing him.
The boy band - Max George, Tom Parker, Siva Kaneswaran, Nathan Sykes and Jay McGuiness - drenched Dr. Todd Swift in the liquid from their room at the Marylebone Hotel in central London, and he claims they branded him US President Barack Obama because of his accent.
Todd - who penned episodes of 'Teenage Mutant Ninja Turtles' and 'Young Robin Hood' in the 1990s - told The Sun newspaper: "What sort of example are they setting to their young fans?
"I came out of the gym and was walking down the street.
"Suddenly I was hit with a lot of liquid. It was not, as the police claim, a glass of champagne. It was a lot of liquid. It went all over my hat, jacket, shirt and face. I looked up to the second floor and there were three young guys laughing at me. One of them said, 'P**s and beer, mate.' "
The 'Walks Like Rihanna' hitmakers were celebrating Jay's 23rd birthday when the incident occurred last week, and they received a ticking off from police.
A spokesman for Scotland Yard explained: "Police were called at around 12.20pm on Thursday, July 25, to a report of a man having been verbally threatened and having had a liquid substance thrown over him at a hotel in Marylebone.
"Officers returned the next day, July 26, and spoke to the party identified. It was ascertained that a glass of champagne had been thrown, but there was no evidence of who, if anyone, had actually done this or been involved in any verbal altercation.
"The victim was informed that without any further evidence there were no further lines of enquiry to pursue."
This comes after Justin Bieber was slammed for appearing to spit at his fans from his hotel balcony in Toronto, Canada, on Thursday (25.07.13).
