MCMC said the suspect went to its headquarters in Cyberjaya, accompanied by lawyers, to give a statement.

“MCMC also seized a mobile phone and a SIM card believed to have been used to publish the content, an action carried out under Section 24 of the Communications and Multimedia Act (CMA) 1998.

“The case is being investigated under Section 233 of the CMA, which provides for a fine of up to RM500,000, up to two years’ imprisonment, or both,” it said in a statement.

Claims previously circulated online that Malaysia was exporting diesel to the Philippines, following a Philippine News Agency report that about 52 million litres of diesel were sent to the country.

The National Economic Action Council (MTEN) later confirmed that the 329,000 barrels of diesel did not originate from Malaysia.

Petronas also denied any involvement in the shipment.

Prime Minister Anwar Ibrahim also dismissed the claim, saying the shipment originated from Vitol, a foreign energy company with operations in Pengerang, Johor.

He said the diesel was not from Petronas and that Vitol is involved in a foreign agreement to ship diesel for sale to the Philippines.
