A senior official of Oil India Limited posted in Mizoram died of cardiac arrest on Thursday morning, police said.
Rupankar Borkataky, 54, of Duliajan town in Assam’s Diburgarh district was found dead by his staff at the OIL’s official guest-house in Aizawl.
Staff had become worried after Borkataky, Head Chemist of the company’s Mizoram operations, did not turn up at the office at the usual time and phone calls to his room remained unanswered.
A senior police officer said his body was already cold by the time staff entered his room and found him lying dead.
Foul play has been ruled after a post-mortem and cardiac arrest is suspected as the cause of death.
His body is being accompanied by other OIL employees to Guwahati.
