Police said a group of rebels went to Pochara Panchayat, about 100 km from Ranchi, last night and blew it up.
The Maoists had killed a policeman, blasted railway tracks, an engine and a mobile tower during the bandh called by them yesterday.
The bandh was called to protest against arrest of Maoist cadres in neighbouring Odisha, sentencing of some cadres in Uttar Pradesh and anti-Maoist operations by security forces.
