Registering a suo motu PIL over the recent death of three elephants in Sambalpur district, the Orissa High Court on Tuesday issued a notice to the state government, seeking to know its measures to check such incidents.

Two full-grown female elephants and a calf died after coming in contact with live wires laid by poachers in the Naktideul range of the Rairakhol forest division in the early hours of Monday, officials said.
