Twenty years ago US police arrested a young Afghan emigrant at his hotel room in Caesars Palace, Las Vegas. The Afghan, who introduced himself as Mr E, tried to sell a bag of heroin to an undercover detective. At his trial, prosecutors said it was worth $2m. *
*The man spent three years and eight months in a Nevada state prison before being released on parole. His wife, who had stood lookout in the hotel corridor, received a probationary sentence. *
*Now Mr E - or Mr Wasifi - is the director general of the Afghan government's main anti-corruption agency. *
*He plays down the 1988 drug bust as a little youthful fun gone wrong. *
"It was my honeymoon. I was a youngster and youngsters do stuff," he said with a shrug during an interview at his modest Kabul office. "Stuff like gambling, drugs" - he rubbed a finger against his nose and sniffed - "and girls. I was a Las Vegas boy."
