Justin Bieber detained at LAX after arriving from Japan

LOS ANGELES (KABC) -- Pop star Justin Bieber caused a commotion at Los Angeles International Airport Thursday.

The singer was detained for hours by Customs officials at the airport after returning from Japan Thursday afternoon.

Officials say Bieber was subjected to a routine questioning session triggered by the pop star's well-publicized legal troubles.

A representative for Bieber had no comment on the incident.

Bieber left the airport Thursday evening without speaking to the media and was driven away in a black van.
