Activist monk Phra Buddha Isara has visited the Crime Suppression Division after being accused of lese majeste.

Accompanied by his lawyer, the controversial monk, who was one of the leading campaigners responsible for ousting the former Pheu-Thai government, reported to the Crime Suppression Division office on Tuesday morning and spent an hour talking with police.

"I had been informed that police investigators came to interrogate people at Wat Orm Noy. I have also been informed that the police are preparing to raid the temple. So, I came today to give information that the police might need," said Phra Buddha Isara, also known as Phra Suvit Theerathammo, abbot of Wat Orm Noy Temple in Nakhon Pathom.

His move came after an accusation of lese majeste was made against him. In April last year, Wichai Prasertsutsiri, coordinator of an organisation that promotes Buddhism, reportedly accused Phra Buddha Isara of producing Buddhist amulets eight years ago bearing the emblem of His Majesty the late King Bhumibol Adulyadej.

The amulets, called Phra Nak Prok, carried the royal emblem but Mr Wichai said he was unsure if Phra Buddha Isara had been granted royal permission to use it.

In addition, some of the monk's blood was allegedly used during the blessing ceremony, which was considered inappropriate. Adverts for the amulets were also found on a number of websites.

Mr Wichai said that if the monk had used the emblem without permission, he may have breached Section 112 of the charter.
