Rijiju till now had 'Z plus' category cover provided by the elite commando unit of paramilitary Central Industrial Security Force (CISF) across India but now this will be further enhanced.
A threat to Rijiju is perceived from a host of insurgent groups for his vocal statements against insurgency, Muslim fundamentalists, stepped-up offensive against militants and the ministerial position held by him, official sources said.
Requisites of security arrangements to be made for a Z-plus protectee are contained in the 'Yellow Book' which are being implemented, the sources said.
A recent assessment indicates a severe threat to Rijiju's life from a newly-formed conglomerate called United National Liberation front of West and South-East Asia comprising NSCN-K, ULFA and other rebel groups.
"Keeping in view the threat quotient of Rijiju, it is imperative that the security arrangements made for him is robust and in tune with the guidelines contained in the Yellow Book," an official order said.
The CISF is therefore advised to review and recalibrate security arrangements made for him so as to plug loopholes, if any, in his security cover, the order said.
Political leaders like L K Advani and Amit Shah and NSA Ajit Doval are being accorded this top category security.
