A family friend says the son of legendary boxer Muhammad Ali was detained by immigration officials at a Florida airport.

Chris Mancini says that 44-year-old Muhammad Ali Jr. and his mother Khalilah Camacho-Ali, the second wife of Muhammad Ali, were arriving at Fort Lauderdale-Hollywood International Airport on Feb. 7 after returning from Jamaica.

Mr. Mancini says officials questioned Ali Jr. for nearly two hours, repeatedly asking him, “Where did you get your name from?” and “Are you Muslim?”

Mr. Mancini says officials continued questioning Mr. Ali Jr. after acknowledging that he was Muslim. Mr. Ali Jr. was born in Philadelphia and holds a U.S. passport.

U.S. Customs and Border Protection spokesman Daniel Hetlage confirmed on Saturday evening that Mr. Ali Jr. was held for questioning by customs officers, but said “it wasn’t because he’s a Muslim and it wasn’t because of his Arabic-sounding name.”
