He said that the officer, who is stationed in Bintulu, lodged a report after receiving several threats from an unknown individual, Utusan Malaysia reported.

“A Petronas officer received multiple threats through SMS and text messages from an unidentified person. After receiving the threats several times, he lodged a police report.

“Therefore, we have advised Petronas to enhance security at all its facilities,” he was quoted as saying after officiating a blood donation programme today.

He added that police contingents nationwide would assist to ensure the safety of Petronas installations.

Yesterday, MKN ordered an immediate tightening of security measures at LNG facilities in Bintulu following reports of a potential security threat.

Petronas meanwhile said that operations at its facilities were unaffected.

Through its subsidiary Malaysia LNG, Petronas operates the Bintulu LNG complex, one of the largest single-site facilities of its kind in the world.

The site houses nine liquefaction plants spread over 111.7ha, an area comparable to more than 200 football fields. Its production capacity stands at about 29.3 million to 30 million metric tonnes a year.

Threat to ‘burn down’ LNG facilities

Separately, deputy prime minister Fadillah Yusof said the text messages were sent from a phone number registered in Indonesia. He said the sender initially sent a “specific request” to the Petronas officer, who ignored the SMS.

“Because there was no response, he threatened to burn our LNG facilities, but who knows which one,” said Fadillah.
