He was asked by officers to make an appearance on his balcony to help disperse the fans eager for a glimpse of their idol.
But Bieber decided not to return to his hotel room after his concert upon hearing that two fans disguised as cleaners had made their way into his suite before being discovered by his security team.
According to Britain's Daily Mirror, Bieber slept on his tour bus after hearing how the 16 and 18 year olds tried to get into his bed.
A source tells the publication, "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.
"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. 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."
