Justin Bieber has been let loose.

After being detained nearly four hours by U.S. Customs after he flew into Los Angeles International Airport, the Canadian pop star was just finally allowed to leave.

He left at around 6:20 p.m. with four bodyguards in tow. Two SUVs and one van had been waiting for the group to emerge from the Tom Bradley International Terminal. Bieber climbed into one of the SUVs and was driven away.

He was smiling as he exited the airport but had nothing to say to the throng of paparazzi assembled outside.
