Two powerful improvised explosive devices (IEDs) were on Monday found planted in a school in insurgency-affected Latehar district, which was identified as a polling centre for the last phase of assembly elections on December 18.
Besides, another IED was found near a camp of the para-military forces in Saraikela-Kharswan district and an alleged supplier of arms was arrested.
Superintendent of Police (Latehar), Kuldip Dwidi said the IEDs, locally known as can-bombs, weighing 20 kgs each, were planted in Khapia Middle School under Balurmath police station.
The bombs were planted to disrupt poll process, he said. The police had seized three similar can-bombs at a place in the same police station area yesterday.
From the arrested arms supplier, a 9 mm semi-automatic pistol and about 500 assorted cartridges were seized, he said. It was being probed whether he supplied arms to Maoists.

The para-military forces had a brief gun battle with the Maoists on Sunday night there, Abhisekh Kumar, superintendent of police of Saraikela-Kharswan district, said.
