Parit Chiwarak, Thanawat Wongchai and Wiranpat Rodkaew went to the OHCHR office in Bangkok to file the petition issued by a student network of 10 universities and institutes.

After meeting OHCHR representatives, Parit, a political science student from Thammasat University, said that the UN body had agreed to continue urging the Thai junta over alleged infringements of human rights.

The OHCHR also expressed concerns about suspected eavesdropping by the Thai authorities over communication devices, especially targeting those considered dissidents by the junta, Parit said.

Thanawat, an economics second-year student from Chulalongkorn University, said that some officers attempted to track him through his faculty, trying to obtain his address and information.

“Luckily, my faculty didn’t contact them back,” said Thanawat, who also serves as a deputy on the university’s student council and has joined noted student activist, Netiwit Chotiphatphaisal, in activities that challenged the junta.

Wiranpat, also a politics student from Chulalongkorn, said two police officers came to her house and talked to her mother on Tuesday, a day after she raised a banner mocking Prime Minister Prayut Chan-o-cha who lectured at her university.

Wiranpat said officers had asked her mother about her activism and whether she had been backed by any political party or paid by anyone.

Her mother insisted she did everything out of her own free will and that she was interested in politics, Wiranpat said.

It was unclear how the officers had obtained her personal information and address, she said.

So far after her activism against Prayut, Wirapat said she had not been pressured by the university. Some democratic activists claim that the institution’s executives back the junta.

“Some may view our actions as betraying our country. They may question why we are bothered to report this,” said Parit, a prominent student activist who was visited by the authorities late last month.

“But the country belongs to all of us. We’re doing everything to enable everyone in this country to live with rights, freedom and dignity.”

The OHCHR did not comment.
