Teen pop sensation Justin Bieber was forced to leave his Liverpool hotel and sleep on his tour bus after his concert on Friday when told that two sneaky and enterprising tween fans have made their way to his suite and took picture of his personal possessions.

Hundreds of fans took to the streets surrounding Hard Day’s Night Hotel in Liverpool, England before Justin’s scheduled concert at Echo Arena last Friday.

With fans storming and staking out outside the hotel, the Liverpool police were reported warning Bieber’s camp not to get out of the hotel nor even show up on his hotel balcony in a bid to avoid riot situation. The police even threatened to arrest the "Baby" hitmaker and the singer’s entourage, should they refuse to cooperate with Liverpool authorities.

But fans wouldn’t let up and the police were forced to take back their earlier warning and asked Bieber to show himself at the hotel balcony to give the fans what they came for asking and hoping for: a glimpse of their pop star, teenage idol.

The police were hoping that the hundreds of fans would be dispersed when Bieber would go out from his room and show up at his hotel balcony that would allow his tween fans for a quick peek.

But for two teenage fans, it wasn’t enough to take a glimpse of their idol. According to Aceshowbiz, Britain’s Daily Mirror described two enterprising 16 and 18-year-olds fans, who had made their way inside Justin’s Liverpool hotel room by disguising themselves as cleaning lady.

"The hotel was swamped by fans all desperate to catch a glimpse of Justin. But two particularly enterprising girls snuck in through a side entrance, and stole two housekeeping outfits," an unidentified source was quoted telling Daily Mirror by Aceshowbiz.

The British paper said that these couple of tween fans dressed themselves as cleaners and successfully made their way into Justin Bieber’s hotel suite.

"After ditching their regular clothes and slipping into their new costumes, they got the lift to Justin's suite and knocked on the door, calling 'housekeeping'. Having been allowed in, the girls began half-heartedly polishing tables and dusting surfaces," the source described the sneaky fans to Daily Mirror.

The two tween fans fun ended when they were discovered by Bieber’s entourage roomed next door, who heard the two making noise.

The source said, "No one clocked on [realised] until the girls were alone, and in his bedroom, taking pictures of his personal possessions on their phones. A member of Justin's entourage in another part of the suite heard them giggling and came through, catching them in the act. The girls, following a telling-off, were evicted from the premises."

The singer then was asked to stay away from the hotel after his concert , leaving him no choice but sleep on his tour bus to get some rest.

As earlier reported by IBTimes, the teen pop sensation is in London as part of his international leg for his “My World” tour. From Liverpool, Bieber was supposed to head to Newcastle, England for more performances.
