Bollywood superstar Shah Rukh Khan’s son Aryan was on Thursday granted bail by the High Court in Mumbai, more than three weeks after the 23-year-old was arrested by the federal anti-narcotics agency in a drugs-on-cruise case. Apart from Aryan, his two friends -- Arbaz Merchant and Mummun Dhamecha -- were also granted bail in the case. But the court added a rider to the bail -- the trio can't leave the country without its permission. However, the three are unlikely to walk out of jail by Thursday night, as the High Court's detailed order will be issued Friday only.

On Tuesday, Aryan's lawyer Mukul Rohatgi argued in the court that the 23-year-old was a "young man who should be sent to a rehabilatation centre rather than jail". Aryan was arrested by the Narcotics Control Bureau (NCB) on October 3 after hours of grilling in connection with a rave party the federal agency busted on board a cruise ship off Mumbai coast a day before. He has been in judicial custody since October 8. Acting on a tip-off, some 30 NCB sleuths, disguised as passengers, boarded luxury cruise liner 'Empress' on October 2 evening, which departed the Mumbai port for the neighbouring state of Goa. The cruise ship was carrying mostly celebrities from Bollywood and the fashion industry. As soon as the rave party began, the NCB sleuths swung into action and claimed to have caught red-handed those having drugs.
