Even as a 48-hour bandh, called by Maoists to protest the recent killing of 10 cadres in Jharkhand, ended, the rebels wreaked havoc on various parts of Bihar in the intervening night of Sunday-Monday — blowing up a sub-station in Jamui district, indulging in arson and taking people hostage, albeit briefly.

About 1,000 Maoists blew up part of the sub-station, affecting power supply. One room was blasted.

In Aurangabad district, Maoists set fire to an Airtel mobile tower in the Kutumba police station area between 11 p.m. and 0000 hours, Monday.

A police operation, along with the Central Reserve Police Force, was still going on, Daljeet Singh, SP, told The Hindu .

In Muzaffarpur district, 25-30 Maoists attacked the premises of Saaj Infracon, a Patna-based company, and briefly took 10-15 labourers hostage to make good their escape. In the incident that took place in the Sahebganj police station area between 0030 hours and 1.30 a.m, “they first set two JCBs [excavating machine] and two tractors on fire. They then took the workers who were sleeping there, including tractor drivers, and the JCB to distance of one kilometre, fearing police retaliation.

In Gaya, four CRPF personnel were injured while defusing a bomb. “About 300 km from a police camp in Sewra, CRPF CoBRA [Combat Battalions for Resolute Action] teams discovered some bombs, embedded in the road. They almost defused one, but it accidentally went off. One civilian also sustained some pellet injuries,” Nayyar Hasnain Khan, Deputy Inspector-General, Gaya, told The Hindu .

“Our search operations along with the CRPF are on,” he said.

The injured jawans were brought to the Patna Medical College Hospital.
