A group of royalists clashed with pro-democracy demonstrators at the Siam Square sky train station today, forcing Pathumwan police and BTS officials to close all entrances to the connected malls.

The Taluwang anti-monarchy group, led by Tantawan Tuatulanon, held a rally at the station to explain an incident in which she was accused of honking a car horn at the convoy of Her Royal Highness Princess Maha Chakri Sirindhorn on an expressway in Bangkok.

Simultaneously, a royalist group rallied nearby to protest against the first group’s activities.

Speaking to the media during the rally, Tantawan offered a public apology for the incident, saying that she was sorry for speeding and was not careful enough.

She was booed and jeered by the royalists, resulting in a clash between the rival protesters, forcing her to end the press conference abruptly.

No serious injuries were reported.

Uniformed and plainclothes police intervened to stop the affray and the rival groups went to Pathumwan police station to lodge complaints against each other.

In 2022, Tantawan was charged with lèse majesté for conducting an opinion poll on royal motorcades.
