A group of persons from Assam were picking up fake currency from the Bangladesh border and bringing it down to South India and circulating the same.
The module boss, Saddam Hussain who was arrested on September 9 2015 at Vishakapatanam with fake currency of Rs 5 lakh had revealed details about the operations.
The NIA's Hyderabad office had taken up this investigation and it had been found that these persons were planning on operating several hubs in South India.
The NIA even arrested one Amirul Hoque a 22 year old resident of Assam from Bengaluru late on February 13.
His name had cropped up during the investigation of Hussain. Hoque was part of the same module that was involved in circulating fake currency in Bengaluru and other parts of South India.
The investigations had found that this module would pick up fake currency from Malda in West Bengal and then bring it to Bengaluru and other cities in South India.
The intention was to circulate fake currency and earn money on a 2:1 ratio. This meant that for every two fake currency notes, they would exchange it for one genuine one.
