Maoists removed fish-plates from track causing derailment of a rake in Jharkhand's Godda district early on Tuesday, disrupting transportation of coal to Bihar's Kahalgaon based NTPC plant.
NTPC sources said the Maoists unbolted fish-plates near Dehri and six empty wagons and an engine, meant for carrying coal from Lalmatia to the plant, got derailed.
The disruption in supply of coal to the plant might affect production of energy at the plant, the sources said.
The ultras left behind leaflets at the site claiming responsibility for removal of the fish plates, they said.
Senior officials of NTPC, railways, CISF, and the district administration rushed to the spot and necessary action was being taken for clearing the tracks for resumption of transportation of coal to the plant.
