The CRPF personnel were on a search operation on Jhumra hills in the district, around 160 km from here, when they spotted a Maoist flag near Jamunia Jora village.
Trooper Basumatari went to remove the flag, which triggered the bomb killing him on the spot.
Maoists have used flag-triggered bombs to trap security personnel in the past also.
