"Lamba was allowed to go at 1 am after 16 hours of questioning and recording of statement. She is likely to be called today as well," a Customs official said.
The 26-year-old actor, who landed at the Chhatrapati Shivaji International Airport from Cannes, France via Dubai by an Emirates flight at 8.30 am on Wednesday, May 18, was crossing the green channel when she was intercepted by the Customs officials.
During checking of her luggage, she was found to be carrying jewellery worth over Rs 50 lakh in her bag.
Lamba, whose debut film ''Yahaan'' garnered critical acclaim, has acted in movies like ''Bachna Ae Haseeno'', ''Corporate'' and ''Well Done Abba''.
She was in France to attend the premiere of Woody Allen's ''Midnight in Paris''.
