Shah Rukh Khan, the Indian actor known as the “King of Bollywood,” said he was detained for a few hours at an American airport on Thursday. Again.

To detain one of India’s biggest celebrities would itself attract international headlines, but this, he said, was the third time that he had been held then released while traveling in the United States.

His treatment at American airports was already a sore point among his fans as well as critics of airport security procedures, with each episode sparking outrage and discussion. Mr. Khan was estimated to have a net worth of $600 million in 2014, making him one of the richest actors in the world, just after Jerry Seinfeld.
