ANTI-GOVERNMENT demonstrators threw paint and daubed graffiti on Thailand’s national police headquarters in Bangkok on Wednesday night, as thousands defied orders banning protests. 

Protesters were angered following a violent response to rallies from the Thai authorities which saw dozens injured on Tuesday when police fired water cannon and tear gas to disperse the crowds. 

Thailand has been rocked by months of rallies and protests led by students and young people demanding the resignation of Prime Minister Prayuth Chan-ocha, who came to power in a 2014 coup. 

They are also pressing for reforms to the monarchy, a once-taboo subject, in the most serious challenge to the Thai Establishment in years.

Tens of thousands descended on the Ratchaprasong intersection in Bangkok’s main commercial district, before marching on the heavily defended national police headquarters. 

Thailand’s parliament was in session debating possible changes to the military-drafted constitution in a bid to end the political deadlock. 

But the protests showed no signs of abating today, with rally leader Panusaya “Rung” Sithijirawattanakul stating: “We came here solely because of our anger.”
