The Criminal Court on Monday denied bail for Panupong "Mike" Jadnok, Parit “Penguin” Chiwarak and Panusaya “Rung” Sithijirawattanakul in a renewed attempt by their lawyers.

The court said there was no reason to change the previous order which denied the temporary releases of the trio due to concern they would repeat the alleged offences.

Mr Panupong and Mr Parit are detained at Bangkok Remand Prison and Miss Panusaya is at the Central Women's Correctional Institution nearby.

Mr Panupong was charged with inciting unrest or sedition under Section 116 of the Criminal Code. He also faces charges of violating the Act on Ancient Monuments, Antiques, Objects of Art and National Museums, and violating Sections 116 and 215 for his role in installing a new plaque to symbolise people’s power at Sanam Luang on Sept 19.

Mr Parit and Miss Panusaya — Thammasat University students — were also charged with sedition, as well as other charges for their roles in the Sept 19 rally at Sanam Luang.

Their lawyers tried to offer higher cash bond for their bail in the hopes of getting them out after the Court of Appeal on Saturday denied them bail.

In any case, their lawyers do not give up and will apply for bail again, starting from the lower court.

"Even though physically, I remain in jail, my heart goes wherever you are," the Thai Lawyers for Human Rights quoted Ms Panusaya as saying after the court decision.

Her statement is clearly directed at student-led protesters.

During a previous visit a few days ago, TLHR described the yong activist as "drastically changed", with her hair cut short and dyed black. The prison administration said later her hair was trimmed for hygiene reasons.

They called for the releases of all detained activists and resignation of the prime minister as a pre-condition for a proposal by Gen Prayut Chan-o-cha for all sides to take a step back.
