Rohith Tandon, from whose law firm police recovered Rs 13.65 crore, was questioned for almost 12 hours by the IT department on Sunday.
The IT officials left Tandon's T&T law firm at 6:30 pm in the evening today.
The Delhi Police Crime Branch and IT officials had raided the office on late Saturday evening and have since then sealed the office. On Monday, the IT officials packed the seized currency into boxes and left the premises.
Tandon arrived on Sunday evening and was questioned for almost 12 hours by the IT department. Approximately 13.50 crores were seized from his law firm, out of which Rs 2.5 crore were in the new Rs 2,000 currency notes.
Tandon is an influential figure in the capital. He started out in 2005 with the law firm ZEUS and went on to start T&T in 2014. This firm looked mainly into real estate, hotels and corporates. Tandon owns a chain of posh properties and had as many as 18 bank accounts in India and a few more abroad.
Sources say that a large part of the money found in the T&T law firm office belongs to a builder based in Ghaziabad.
Speaking to India Today, an IT official said, "We seized around Rs 13.50 crores. No names have come up yet. The investigation is still going on."
