The uniformed policeman who addressed the red-shirt rally on Tuesday would be subjected to a disciplinary investigation, city police spokesman Maj-General Piya Uthayo said yesterday.
The Police Aviation Division's Pol Senior Sergeant Major Ubon Suwanklang's behaviour was reported to his supervisor by the Metropolitan Police, Piya explained.
He added that the officer would have to undergo investigation because voicing personal political opinions while in uniform is a disciplinary offence, though it is not too severe. Investigators will check if Ubon had been addressing the protesters while on duty. The investigation team would also determine if Ubon's speech could be considered a libel offence, for which he might face legal action, Piya said.
He went on to say that a memo had been issued a long time ago warning officers to not get involved in political protests while in uniform and only express neutral viewpoints when on duty.
