The NCB arrested Anant Vardhan Pathak, a top executive of the group, his peon and security officer last night from a five-star hotel.
All the three were produced before a local court which remanded them in NCB custody till January 16.
Rohit Katiyar, zonal director of NCB, confirmed the arrest but refused to divulge any further details, saying an investigation was under progress.
The case came to light after the investigation department of Income Tax conducted a search at a five-star hotel in South Mumbai in connection with taxation purposes against the Group last week.
When the sleuths went to the hotel room where Pathak was staying and started conducting searches, they found some contraband.
