"Following an initial internal enquiry, two employees -- Ganpat Singh and Gaurav Jain-- working in the accounts department have also been identified to have been in possible collusion with Sanjay Gupta and Citibank employees," Hero Corporate Service said in statement.
Earlier this week, Gupta was remanded to a five-day police custody in connection with the Citibank fraud case for allegedly investing about Rs 250 crore belonging to promoters of the Hero group companies.
The Gurgaon police arrested him under the section 120B of the Indian Penal Code that deals with criminal conspiracy.
According to the police, Gupta had invested around Rs 250 crore from different Hero Group companies and their promoters.
For this, Gupta had formed two finance companies -- BG Finance and G2S, and took commission of Rs 20 crore from Shivraj Puri, the alleged mastermind in the estimated Rs 300- -crore fraud discovered at the Citibank`s Gurgaon branch, for investing the amount.
The police had last week called Gupta for questioning along with Puri.
Puri had confessed that Gupta was aware of the forged SEBI letter, on which the amounts were lured from high networth clients, the police had said.
