Rijiju till now had 'Z' category cover provided by the elite commando unit of paramilitary CISF across India.
The decision has been taken after an intensive review of his security cover by intelligence agencies.
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.
"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.
