Pop star Justin Bieber left Los Angeles International Airport late Thursday after being detained for several hours, KABC-TV reports.
Bieber, 20, offered no comment as he left. According to his Twitter account, he left from Japan earlier today.
U.S. officials told ABC News he was subjected to a routine question-and-answer process.
It's not uncommon for customs and immigration officials to question non-citizens who arrive in the US and have open legal proceedings. The Canadian was briefly detained in February when his private jet arrived from Canada to New Jersey for Super Bowl festivities.
His rep also had no comment when contacted by ABC News.
Earlier this week, Bieber apologized for tweeting an homage to the Yasukuni Shrine while he was in Japan.
"While in Japan I asked my driver to pull over for which I saw a beautiful shrine," he explained via Instagram. "I was mislead to think the shrines were only a place of prayer. To anyone I have offended I am extremely sorry. I love you China and I love you Japan."
