Police have issued summonses for 12 core members of the Khana Ratsadon anti-establishment group, to acknowledge charges of lèse majesté, among others, for their leading roles in protests demanding sweeping reform of the Thai Monarchy.

The police’s decision to invoke the infamous Section 112 of Thailand’s Criminal Code comes ahead of a mass protest today, organized by the Khana Ratsadon group and others, expected to take place at the Crown Property Bureau.

The 12 Khana Ratsadon leaders facing charges are:

Parit “Penguin” Chivarak – eight cases pending
Panasaya “Rung” Sitthijirawattanakul – six cases pending
Panupong Jardnok or Mike Rayong – four cases pending
Anon Nampa – four cases pending
Passaravalee “Mind” Thanakitvibulphol – three cases pending
Chanin Wongsri – two cases pending
Chuthatip Sirikhan – one case pending
Tadthep Ruangprapaikitseri – one case pending
Atthaphol Buapat – one case pending
Chukiat Saengwong – one case pending
Sombat Thongyoi – one case pending
Piyarat Chongthep – one case pending

It is reported that police in several districts have sought arrest warrants, but the courts have rejected their requests on the grounds that these protest leaders are public figures and are of fixed abode. The court recommended that the police issue summonses instead.

Parit said, in his Facebook post, that he received the summons, on two charges, at his residence last night, namely lèse majesté and violation of the Computer Crime Act, adding that he is not worried about the charges “because the ceiling has already been broken.”

He also posted a notification of change of venue for today’s protest muster point, from the Democracy Monument to the head office of the Siam Commercial Bank.

In her Facebook post today, Panasaya said police came to find her last night at her university. She told the police to show her the summons and not to come looking for her at night.

The SCB head office is closed today, ahead of the arrival of protesters, as police erect barriers to prevent protesters from getting near the bank on Ratchayothin Road. Additional CCTV cameras were also installed around the bank.

Throughout last night, authorities placed cement and plastic barriers on roads around the Crown Property Bureau. Thousands of police have been deployed around the bureau to maintain law and order.
