Earlier, the investigating teams had sought the help of Interpol to trace the bitcoins. The cops managed to identify some cryptocurrency firms outside India where the hackers had used the bitcoins, but got no further information.
Confirming the developments, DCP (cyber cell) Anyesh Roy said, “We contacted some of the exchange firms from where the bitcoins were routed. Initially, they didn’t give a response, but now we are in the process of getting the information through mutual legal assistance treaty.”
