"The arrest of former Rashtriya Swayamsewak Sangh (RSS) worker Kamal Chauhan by the National Investigation Agency (NIA) shows that the saffron organisation is busy spreading terror," Bhuria said in a statement.
"This man (Chauhan) had received training at Karna Singh Shooting Range of Faridabad in Harayana. He was trained in handling explosives at Bagli in Madhya Pradesh," he said. The NIA took into custody the Indore-based former disgruntled RSS worker for his alleged role in the 2007 train attack.
Chouhan is believed to be a close aide of Ramji Kalsangra and Sandeep Dange, key accused in the case.
