The CPI(Maoist) triggered a landmine blast at Baramara in Ghatsila sub-division of Jharkhand today, the first day of the 48-hour bandh by the outfit in five states but there was no casualty or damage.
East Singhbhum superintendent of police Navin Kumar Singh, who rushed to the spot, said the Maoists had targetted an anti-landmine vehicle but could not cause any major damage to it.
A combing operation has been launched in the area, adjacent to West Midnapore district, in which Lalgarh is located, to flush out the extremists from there, Singh said.
Stringent security measures have been taken up by the East Singhbhum district and the police there were alerted, particularly in Ghatsila, due to its proximity to Lalgarh.
The Maoist outfit has called the bandh to protest against the combined security forces operation at Lalgarh.
