Screenwriter Paul Laverty, husband of Icíar Bollaín, arrested in Edinburgh on terrorism charges for wearing a T-shirt supporting Palestine Action.

Scottish filmmaker Paul Laverty , who has worked on scripts for Ken Loach 's films, was detained in Edinburgh for several hours for expressing his support for the Palestinian Action organization, which has been banned in the United Kingdom , The National newspaper reported on Monday.

The award-winning screenwriter, who is the partner of Spanish film director Icíar Bollaín , faces terrorism charges for wearing a T-shirt that read "Genocide in Palestine, time to act," which the newspaper said was an endorsement of the organization.

Scottish police were unable to provide details about this arrest after being contacted, as it was a public holiday in the United Kingdom.

After the arrest, Laverty told supporters gathered outside the police station that law enforcement acts like a "Mickey Mouse court," the newspaper reported.

"It's quite surreal to be fingerprinted and tested at 68 years old, without ever having had any trouble with the police," said the screenwriter, whose statement the newspaper posted on its website alongside a photo of him.

"But it's an interesting ritual, and I must say, there was some humor in it, because apparently the T-shirt was banned. It's quite funny. I've been charged with terrorism and will appear in court on September 18. They're accusing me of terrorism, they're accusing me of terrorism because I oppose famine, the execution of those who are starving," he stressed.

"Now you can see how the judicial system is biased, not in our favor. You can see how the ICJ (International Court of Justice) has been weakened. You can see how the ICC (International Criminal Court) has been weakened," he noted.

"So the entire judicial system simply doesn't work, and even though we have the law on our side, we can't implement it. That's why I think we have to change the narrative. I think we'll have to remember that the most important court in the world is the court of public opinion. Ordinary people are appalled by the famine, the genocide, and the sale of arms to the apartheid state of Israel," he added.

Irish writer Sally Rooney recently received a warning from the British government that she could face terrorism-related charges if she donates money to Palestine Action, which was recently outlawed by the UK government.

The author of hits like "Normal People," adapted for the small screen by the public broadcaster BBC, announced last week that she will donate part of her profits from her books and television adaptations to "Palestine Action."

Rooney, 34, announced in an article in The Irish Times that he will donate profits from his work and public profile to continue supporting Palestine Action and "direct action against genocide in any way he can."

Since last July, Palestine Action has been classified by law as a terrorist organization in the United Kingdom, after some of its members vandalized two aircraft at a Royal Air Force (RAF) military base and blocked the entrance to the headquarters of the Israeli defense company Elbit Systems in Bristol (southwest England).

Under this law, the London Metropolitan Police (Met Police) made more than 500 arrests on August 9 at a peaceful demonstration in Parliament Square in support of "Palestine Action."
