BANGKOK (AP) — Thailand’s prime minister on Wednesday offered his condolences to the family of a young activist who died in detention after a monthslong hunger strike, amid a public debate on the country’s justice system.

Netiporn “Bung” Sanesangkhom, 28, died on Tuesday after suffering cardiac arrest while she was being detained at Bangkok’s Central Women’s Correctional Institution on charges that included defaming the monarchy. She had been on a hunger strike to protest the revokation of her bail in January.

Her death has prompted calls for reviewing a judicial process that allows people accused of politically-motivated, nonviolent offenses to be held for extended periods ahead of trial.

Prime Minister Srettha Thavisin told reporters that Netiporn’s death was a loss that no one wanted, and said he has ordered the Justice Ministry to investigate.
