On 17 March, Phromson Wirathammachari, a protester well-known for his speeches, went to hear a charge of lèse majesté at Thanyaburi Police Station but the police suddenly handed him over to the court, with a request to detain him.

According to TLHR, the court denied Phromson bail, citing the gravity of the charge, the severe penalty, and the likelihood that he would either flee or repeat the offence. The decision led to him being detained at Thanyaburi prison even though was seriously injured from a traffic accident,.

Sasinan Thamnithinan, a TLHR lawyer who went to the police station with Phromson, posted on Facebook an account of the police haste. The post stated that although Phromson came to the station with his injuries to prove that he had no intention to flee, the deputy superintendent (investigation), after the regular investigation stage, suddenly decided to take him to court before the court closed.

Sasinan doubted the police decision because for a detention request, the appointment at the station would be for the morning instead of the afternoon. The police also expressed uneasiness at her attempt to consult with Phromson over this sudden turn of events. The station superintendent gave them 2 minutes to consult in private.

Without being prepared, Sasinan wrote the bail request as fast as she could. However, the court denied bail, giving similar reasons to those in Chukiat’s case.

TLHR reported on 22 March that at least 76 people have been prosecuted under the royal defamation law in 66 cases. 27 cases were filed by ordinary citizens, 5 by the Ministry of Digital Economy and Society and the rest by the police. 4 of the accused are under the age of 18.
