Singer Lata Mangeshkar says that Bollywood superstar Shah Rukh Khan’s surname might have been the reason for his detention for a second time at a US airport. Shah Rukh, 46, was detained and questioned in New York for two hours on Thursday, sparking outrage in India. The first time he was detained, the actor happened to be promoting My Name Is Khan (2010).When asked to comment on the incident, Lata said, “What do I say... I guess it might be due to the terrorist attacks which have made them (US authorities) more alert. It may be due to his surname. I don't know why it happened. They might be suspicious,” she said. “I feel Shah Rukh has become slim, lost weight so they could not recognise him," Mangeshkar said jokingly.
