Justin Bieber’s latest run-in with the law: detainment by U.S. Customs officers.

The Canadian pop star was held at a U.S. Customs and Border Patrol area of Los Angeles International Airport on Thursday after he landed in California from Tokyo. He was stopped for routine secondary questioning as a foreign national, his publicist confirmed to EW. Despite a petition to deport the 20 year-old from the U.S., he was not barred from entering the country. Reports say Bieber was held in the Tom Bradley International Terminal for nearly four hours before being released. He left with his entourage, which had been waiting for him.

On Wednesday, Bieber’s attorneys asked for his Miami case involving driving under the influence and other charges to be delayed. That trial will now take place in July.

The singer is also being investigated for vandalism charges in Los Angeles County.
