Security forces carried out massive combing operations in the forests of Dumka and Pakur, officially declared Maoist-hit districts in Jharkhand, on Wednesday, a day after a top police officer and five policemen were gunned down by the ultras but made no headway in tracking them down.
"The security-men have launched an operation to take strong action against the extremists," Anand Shankar, the adviser to Jharkhand Governor Syed Ahmed, said.
"If necessary, assistance will be sought from the Centre," Shankar, who is in-charge of the state Home department under President’s rule, told reporters in Ranchi.
Yesterday's Maoist ambush on a police convoy near Kathikund in Dumka district bordering Pakur, about 400 km from here, would be investigated, he added.
Terming the killing of Pakur SP Amarjit Balihar and other policemen a cowardly act, the governor said a strong response would be given to the Maoists.
The sacrifice of the security-men would not be frittered away and the killers would be caught and brought to justice, said Shankar.
He added the ambush would not lessen the morale of policemen and they would fight with renewed vigour.
