Most of the crowd were young protesters who had gathered in the pouring rain on the Thammasat University campus. They also demanded a reform of the monarchy, which provoked harsh reactions from more conservative sections of society.
According to the police, by the evening about 15,000 people are still at the campus, and during the day there were about twice as many, that is, about 30,000. In addition, musicians entertained the crowd between performances.
The events take place on the 14th anniversary of the military coup that toppled Prime Minister Thaksin Chinnawatu.
Prayut Chan-Ocha promised that the authorities will apply "soft measures" to the protesters "because they are children."
Chan-Ocha has been prime minister since 2014 when a military coup took place in the country. The military coup in Thailand took place on May 22, 2014. The military announced the dissolution of the Senate, the introduction of martial law, and the detention of a number of political and public figures.
