A group of suspected Maoists reportedly attacked a police convoy in Dumka district on Tuesday.
At least five policemen including Pakur Superintendent of Police Amarjit Balihar are feared to have been killed in the attack. "Two vehicles were ambushed in which five persons were killed including Amarjit Balihar," Director General of Police Rajeev Kumar told CNN-IBN.
"It was an ambush and they were fired upon," he added.
Balihar along with several constables was returning to his office in Pakur from Dumka after a meeting called by the area DIG Priya Dubey, when their vehicles were attacked.
According to reports, police force and Maoists are engaged in a gun battle. Additional forces have rushed to the site.
The encounter took place on the Pakur-Dumka border when the SP was returning. The naxalites had placed landmines to trap the SP and constables and fired indiscriminately at them.
Last week, police had discovered three landmines in Chatra district of Jharkhand foiling Maoists' plan to attack security forces.
The attack happened nearly 15 days after Maoists attacked a passenger train passing through Jamui station in Bihar on 13 June. At least 100 Maoists were involved in the attack, said Madhuresh Kumar, General Manager of East Central Railways.
