Aussie arrested in Bangkok over Malaysia criticism

An Australian man arrested in Thailand on a defamation charge he says originated with Malaysia's government, says he is a victim of transnational repression, in which Southeast Asian countries co-operate in seizing critics.

Independent scholar and writer Murray Hunter, 66, told The Associated Press he believes he was improperly arrested by Thai police on Monday for articles he had written about Malaysia in 2024 on his online Substack newsletter.

He questioned how his case falls under Thai jurisdiction.

Concerns about cross-border repression have been documented by groups such as Human Rights Watch and UN rights experts.

In a July report they expressed "profound concern regarding the reported rise in transnational repression ... to deter, silence or punish dissent, criticism or human rights advocacy".

The report to the UN Human Rights Council said suspected human rights violations also included serious claims of extrajudicial executions and enforced disappearances implicating Thailand, Laos, Cambodia and Vietnam, allegations that all those countries have denied.

Hunter, who lives in southern Thailand, was arrested on Monday at Bangkok's Suvarnabhumi Airport as he was about to board a flight to Hong Kong.

He was jailed overnight and then released on 20,000 baht ($A934) bail, pending a November 17 court appearance.

The charge of defamation by publication against him is punishable by a maximum prison term of two years and a fine of 200,000 baht ($A9378).

Hunter blamed the Malaysian Communications and Multimedia Commission for lodging the criminal defamation charge against him.

A copy of his charge sheet, seen by AP, identifies that agency as the victim in the case, but says the complainant was a person staying at a hotel in Bangkok, who it did not name.

The commission said it lodged police reports in 2024 in both Malaysia and Thailand regarding material by Hunter about Malaysian institutions, and filed a civil lawsuit against him in Malaysia.

It said in a statement it understood he had been arrested by Thai authorities for non-compliance with summonses they had issued in connection with their investigation. It also said it would abide by the decisions of the Thai justice system.

Asked about the summonses, Hunter said one was delivered to his home when he was on an extended stay in another region of Thailand and the local police where he was staying advised him the copy forwarded to him by a neighbour appeared to be a scam.

The Thai Foreign Ministry said it could not immediately comment.

A joint statement issued by Malaysia's Centre for Independent Journalism and the free speech organisation PEN Malaysia condemned the arrest.

The statement said that if the commission was involved in the arrest, seeking a cross-border arrest for political criticism goes against the spirit of Malaysia's constitution and its protections for freedom of expression.

"Although the government may reference legal grounds under current restrictive laws, using Thai public authorities to silence dissenting speech would be an overreach of its powers and jurisdiction, and weaken constitutional guarantees," it said.

Hunter said his case should be cause for wider concern.

"If this can happen to me, any journalists now, where a body in another country makes a complaint against them to the Thai police, could have the same consequences and be picked off a flight and put in a lockup," he said.
