However, the NGO has termed it as an attempt to clamp down on its protests against Essar and Hindalco's proposed coal mine in Mahan forest of Madhya Pradesh.
Acting on a tip-off that NGO Greenpeace was using high frequency communication equipment, police had sent a notice to its office at Amelia village in Singrauli to find out whether it was having any licence or authority from local police to use it, Rewa Range Inspector General Pavan Shrivastava said.
In the melee, those present in the office escaped with other high frequency equipment normally used by security agencies for communication purpose, the IG said.
Singrauli Collector M Selvendran said the NGO was using a very high frequency to operate its wireless sets, normally banned for private use and used by security forces, without any licence, as per the district administration's knowledge.
A notice was given to them in this regard but so far they have not responded to it, the Collector said.
Two persons were arrested after police personnel were prevented from discharging their duties by the NGO employees and supporters and they were produced in a local court today, Singrauli's Superintendent of Police D Kalyan Chakravarthy said.
