Heavily armed Maoists blew up the Khaira Block office, destroyed official files and torched 12 sand-laden trucks late on Thursday night in the district, during their two-day East Bihar and Jharkand bandh agitation, police sources said on Friday.
"Over 50 heavily armed Naxals triggered a dynamite blast to blow up the Khaira block office," they said, adding that the ultras later burnt the official files.
They also set 12 sand-laden trucks on fire at Gidheshwar Ghat under the Khaira police station area in the district, sources said.
No causualties were reported in these incidents, they added.
To protest the arrest of five of their leaders from various places in Bihar and Jharkhand, the Maoists had given a two-day bandh call in East Bihar and Jharkhand.
Two days ago, Naxals had burnt two mobile telephone towers, blown up a railway cabin and set several vehicles on fire in Bihar's Jamui and Banka districts.
