Justin Bieber has allegedly been detained at Los Angeles International Airport while trying to re-enter the United States.
Eye-witnesses have said that Bieber was pulled aside by US immigration officials after departing an Air Singapore flight from Tokyo today (April 24), reports E! News.
Bieber has apparently faced two hours of questioning from officials, although it is not yet known why he has been allegedly detained.
His entourage are said to be waiting for the questioning to end.
Representatives for the singer have thus far issued no comment on the matter.
Bieber is currently facing two potential legal cases for suspicion of driving under the influence in Miami and suspicion of assault on a limo driver in Toronto.
Earlier this week, Bieber was forced to apologise for sharing pictures on Instagram of his visit to a controversial war criminals shrine in Tokyo.
