New Delhi, Mar 14 (IANS): The Enforcement Directorate (ED) on Thursday moved a court here, seeking custodial interrogation of corporate lobbyist Deepak Talwar in a case related to the purchase of 43 aircraft by Indian Airlines in 2005.

ED's Special Public Prosecutors D.P. Singh and Nitesh Rana told Special Judge Santosh Snehi Mann that custodial interrogation of Talwar is necessary to ascertain the money trail and to take the investigation to a logical conclusion.

The prosecutors have requested the court to issue a production warrant against Talwar, who is in judicial custody in another money laundering case related to his suspected role in the irregular seat-sharing on Air India's profitable routes with some international airlines.

The court will hear the matter on Friday.

The ED is also probing various other cases related to money laundering against Talwar who was deported from the United Arab Emirates (UAE) on January 30.
