Corporate lobbyist Deepak Talwar has links with fugitive liquor baron Vijay Mallya, the Enforcement Directorate (ED) told a Delhi court on Thursday while seeking extension of his custodial interrogation.
Without giving any further details, the Directorate said: "Investigation is going on over the link between Talwar and Mallya."
Talwar was presented before the court on expiry of his seven-day ED custody.
The Directorate told the court that Talwar's custody is required as he needs to be confronted with documents as well as his son Aditya Talwar and his associate Yasmine Kapoor.
Talwar counsel opposed the plea, saying that Talwar was forced to take names of politicians and forced to say that some companies were his.
Talwar was deported from the UAE on January 30 night. He was presented before a court on January 31 which remanded him to seven-day ED custody.
The ED said that Rs 200 crore was allegedly received in one of the bank accounts of a company of Talwar in Singapore and that he is being probed for his suspected role in the irregular seat sharing on Air India's profitable routes with some international airlines.
Talwar had fled to Dubai after the Indian agencies started probing his role in concealing the income of more than Rs 1,000 crore as well as facilitating aviation contracts during the UPA regime.
He is accused of brokering aviation sector deals, getting government approval in foreign companies, securing favours for clients and having ties with UPA functionaries.
