Patna, Feb 16 (IANS) Maoist guerrillas torched a mobile tower in Bihar's Jamui district on Tuesday, the second day of a two-day state-wide shutdown, police said.

The Maoists had called the shutdown to protest the killing of one of their top-ranking leaders in a police shootout earlier this month.

Nearly 40 armed guerrillas attacked the BSNL mobile tower at Mudwaro village and set it ablaze.

"The BSNL mobile tower was badly damaged," a police official said.

Maoists pasted hand written posters at different places in the district, warning police to stop harassing innocent people and threatened the police to stop torturing the poor.

The shutdown has affected normal life in rural ares in Jamui, Banka, Munger, Lakhisarai and other neighbouring districts.

Maoists blew up a portion of Barhat block office on Monday.
