The allegations stem from their news coverage last March of an activist spray painting an anarchist symbol and the number 112 with a strike through it on the wall of the Temple of the Emerald Buddha, located within the Grand Palace compound in Bangkok.
The number 112 is a reference to the "lese majeste" law that protects the palace from criticism and carries a maximum jail sentence of up to 15 years for each perceived royal insult, a punishment widely condemned by international human rights groups as extreme.
The graffiti incident was captured on video and widely reported by the media.
Prachatai news editor Tewarit Maneechai said the two journalists went to cover the story without knowing in advance that the activist was going to graffiti the temple's wall.
"They were covering the news as journalists," Tewarit said. Police Lieutenant Colonel Phawat Wattasupat, deputy superintendent of Phra Ratchawang police station, told Reuters that police had sufficient information to support their arrests.
Tewarit said his colleagues were not aware of the charges prior to their arrest even though the warrant was issued last May.
"Their arrests created fear about news coverage of sensitive issue," he said.
Thai Prime Minister Srettha Thavisin said on Tuesday that the government is "fair" on freedom of the press and said it is up to the police to see what is appropriate.
"Everything depends on the law, there are no harassment," he said.
The two reporters were detained overnight and will be taken to court on Tuesday to formally hear their charges. The two are applying for bail, according to their lawyers.
