The CPI(Maoists) on Friday triggered three improvised explosive device (IED) blasts in Jharkhand's West Singbhum district when security forces were carrying out search operations but nobody was injured in the explosions, a senior police officer said.
Superintendent of Police Ashutosh Shekhar said the security forces were carrying out search operations in Tumbahaka forest when the IEDs exploded.
However, all the personnel of law enforcing agencies were safe and no injury was reported in the incident, the SP said.
The search operation was going on in the forest, he added.
