Maoist ultras blew up the building of a state-run primary school at village Gerua under Belhar police station in Bihar's Banka district in the wee hours today, police said.
The district administration had earlier planned to set up a police post at the school, they said. Over 100 ultras surrounded the building at around 2.30 am, and used dynamites for the explosion, causing roofs of the three-room school cave in.
The school's furniture were badly damaged, sources said. The school was adjacent to the Sangrampur block office which was blown up by the Maoists last week. Senior officials reached the spot and combing operation was on in the area to arrest the ultras.
