An ED source told PTI that Amit Banerjee was arrested shortly after he went to the directorate office here.
Banerjee, he said, was raising money by floating different schemes from the public and was repaying back the debenture holders of Rose Valley out of the crime proceeds.
The ED had filed a case on the basis of a SEBI complaint that Rose Valley was illegally issuing debentures to the public, following which its chairman Gautam Kundu was arrested.
ED had earlier issued summons to him which he did not respond and instead went to the Calcutta High Court for getting a breather.
The High Court asked him to go and report to the ED office.
The IT returns of Banerjee showed he received a commission of Rs 1 crore from Rose Valley which was believed to be under-disclosed.
