Prinn Panitchapakdi, former deputy leader of the Democrat Party, faces an additional two years imprisonment following a sexual assault conviction.

According to Kosonwat Intuchanyong, spokesperson for the Office of the Attorney General, on 25 September 2023, the Bangkok South Criminal Court delivered verdicts against Prinn in two separate sexual assault cases. One involving charges of public indecency was dismissed due to insufficient evidence.

Prinn was found guilty in a second case involving the sexual assault of a girl under the age of 15, however. He was sentenced to two years without suspension. The court ordered the sentence to run consecutively with the two years in prison he must serve for his conviction in an earlier sex crime case which concluded in August 2023.  As a result, he now faces a total of four years and eight months in prison.

The court granted Prinn temporary bail of 300,000 Baht.

On 10 August 2023, the Bangkok South Criminal Court delivered a verdict in a case in which Prinn was accused of sexually assaulting an 18-year-old woman.  In 2021, he reportedly used the ruse of career discussion and stock market guidance to deceive his victim at a Sukhumvit Soi 11 rooftop restaurant.

On 10 August, the court sentenced Prinn to two years and eight months in jail without suspension. The victim reported the case on April 2022. It was the first he faced.
