President Donald Trump asked on Twitter whether the three UCLA basketball players released from detention in China on Tuesday will thank him for his help.

UCLA freshmen LiAngelo Ball, Cody Riley and Jalen Hill, who had been detained in China for the past week on suspicion of shoplifting, landed in Los Angeles on Tuesday evening and boarded a van to return to campus.

Trump, who returned late Tuesday from a trip through Asia, said he raised their case with President Xi Jinping of China during a visit to Beijing last week.

The players were questioned last week about allegedly stealing sunglasses from a Louis Vuitton store next to the team's hotel in Hangzhou, where the Bruins had been staying before leaving for Shanghai to face Georgia Tech on Friday. They were released on bail early Nov. 8 and had been staying at a lakeside hotel in Hangzhou prior to flying home.

"Our president said to Xi, 'Do you know anything about these knuckleheads that got caught allegedly stealing?'" John Kelly, the president's chief of staff, told The New York Times. "The president was saying, 'It's not too serious. We'd love to see this taken care of in an expeditious way.'"

A source told ESPN's Arash Markazi that there is surveillance footage of the players shoplifting from three stores inside a high-end shopping center, which houses Louis Vuitton, Gucci, Yves Saint Laurent and Salvatore Ferragamo stores.
