A committee for student discipline will also investigate a group of students that vice rector Assoc Prof Bancha Chalapirom said had failed to honour an agreement with the university to pay respects by standing and bowing their heads, the website said.
Both panels would investigate the incident with independence and transparency while maintaining the law and university regulations, the website said.
The alleged assault by assistant rector Reungwit Banjongrat on a fourth-year economics student, who abruptly walked out of the ceremony along with Student Council President Netiwit Chotiphatphaisal, was captured in pictures that were widely shared on Facebook.
