New Delhi, April 7 (ANI): Bollywood actor Akshay Kumar, who is busy filming his upcoming action film 'Rustom' these days, had a bad experience at London's Heathrow airport recently. If reports are to be believed, the 'Airlift' star was detained at the airport as he did not have a valid visa. According to the officials, there were discrepancies in the documents of the 48-year-old actor. The actor was made to wait in the general waiting area of the airport for approximately one and a half hour with other detained passengers. Khiladi Kumar reportedly asked the airport officials to make him sit at a private lounge, but his request was denied. Akshay will be seen playing the role of a naval officer in 'Rustom' which is scheduled to hit the theatres on August 12.
