Brit Author Denied Entry to U.S. for New York Underworld Party

Mr. Horsley, whose memoir, “Dandy in the Underworld,” was published last week in paperback by Harper Perennial, a unit of HarperCollins, said he was detained by United States customs authorities for eight hours and questioned about his former drug addiction, use of prostitutes and activity as a male escort.

“I’m absolutely shattered and upset and gutted about not being able to come to America,” Mr. Horsley said in a telephone interview from London, where he had returned on Wednesday. “I was very much looking forward to meeting everybody.”

Lucille Cirillo, a spokeswoman for the New York office of United States Customs and Border Protection, said she could not comment on specific cases. But in an e-mail message, she said that under a waiver program that allows British citizens to enter the United States without a visa, “travelers who have been convicted of a crime involving moral turpitude (which includes controlled-substance violations) or admit to previously having a drug addiction are not admissible.”
