A 34-year-old US citizen booked for allegedly smoking on board an Air India flight and unruly behaviour towards the crew was granted bail by a court in Mumbai on Monday, police said.

The passenger was found smoking in the lavatory of London-Mumbai flight AI130 on March 10 and behaved in an unruly manner with the crew after they were alerted by the smoke alarm and threw the cigarette from his hand, the official said.
