Khalistani separatist Lakhbir Singh alias 'Rode', a designated terrorist under the Indian law, has died recently in Pakistan, where he had taken refuge after his uncle Jarnail Singh Bhindranwale was killed in 1984 during an army action, officials said on Tuesday.
A senior official said that the state had sought several companies of paramilitary forces and these have been provided to maintain law and order situation.
The ISYF is supported by Pakistan's intelligence agency ISI.
The National Investigation Agency (NIA) has arrested a most-wanted terrorist, carrying a reward of Rs 5 lakhs, from the Delhi airport three years after he was declared an absconder and the Interpol issued a red corner notice against him.
