Munger, Aug. 21: The Munger police have zeroed in on the so-called mischief mongers who sent threat-letters bearing the name of ISIS to the Munger commissioner, Liyan Kunga and the deputy inspector-general (Munger), S.P. Shukla.

The persons involved in such terror-generating activities would soon be nabbed, the police claimed on Friday.

The Munger superintendent of police (SP), Varun Kumar Sinha, said: "The police have identified two different groups who have circulated threat-letters to the officials separately, in the past week."?

"ISIS (Islamic State of Iraq and Syria), a terror group, which has strong bases in Western Iraq and the Eastern Syria, has no branch in any part of India. The terror group is involved in establishing a state in Iraq and Syria. It is not believable that it is involved in Indira Aawas Yojna projects or in the recruitment procedure of assistants and accountants," he added.

The SP further said it was the work of disgruntled applicants who had been denied jobs under the yojanas in 2014. these candidates had circulated the threat letters to the different officials.

?Meanwhile, a special task force, headed by sub-divisional police offier Lalit Mohan Sharma, has recorded the statements of six men, working at the Commissioner's residence and his confidential section. All six were on duty at the commissioner's residence or at his confidential section at eight in the morning on August 20.

This is when the threat letter was pasted on the outer wall of his residence and some were also thrown into the residential campus.

The special task force also found the tube of gum, which was used in pasting the letter.

Threat letters bearing the name of the terror group were found at the commissioner's residence, which threatened him and his family, if he failed to pay Rs 50 lakh as extortion.

The official had alerted the police immediately and security was beefed up immediately. Investigations were started based on the content of the letter, which demanded recruitments under the different yojanas.

This sparked suspicion that it was probably an unsuccessful candidate who was behind this mischief.

A senior police officer, on condition of anonymity, said: " The police have zeroed in on one disgruntled candidate who failed to get a job in the Indira Aawas Yojna, last year. He lives in the Munger Muffasil area, and the police have raided his house today. Details are awaited." ?

S.P. Shukla said: "The police have accelerated the pace of investigation."
