An e-mail by suspected Maoists, received at the Orissa Chief Minister’s Office (CMO) here threatened to blow up the residence of Naveen Patnaik and other important establishments in the state, officials said on Sunday.

The mail suggests bullet injuries to top Maoist leaders Kishenji and Bikram.

“We will reply to each bullet those hit Kishanji and comrade Bikram,” said the e-mail received on Saturday purportedly sent by the Central Military Commission (CMC) of the Peoples’ Liberation Guerrilla Army (PLGA), a Maoist outfit.

“As soon as you launch joint special operation or ‘Green Hunt’, we will start attacks at Bhubaneswar, Cuttack and Puri simultaneously,” the e—mail has said.

Asking the chief minister not to rejoice over the deployment of central para—military force (CPMF) in the state, it said, “Your happiness over getting additional force is temporary“.

Describing the police personnel as a “helpless lot” in the administrative set up, the e—mail has threatened to target corrupt bureaucrats by the use of ultra—modern weapons available under cyber technology.

The state secretariat, office of the commissioner of police, police headquarters in Cuttack, armoury of 6th Battalion of OSAP (Orissa special armed police), Orissa Computer Application Centre (OCAC), Grid Corporation of Orissa (Gridco), Nalco and Biju Patnaik University of Technology (BPUT) are identified in its target.

Claiming PLGA had successfully hacked the state government portal on March 11, the e—mail said the rebel’s acts would be more devastating this time as they were aware of the loopholes in the government set—up.

A senior official of the home department said that they are probing the incident.
