Monash University Malaysia and Curtin University Sarawak Malaysia have warned their students that action could be taken against them for participating in "illegal gatherings".
Students from both institutions have informed Malaysiakini that the notices were received through email over the past two days.
"You are advised not to participate in any illegal gathering/related activity which contravenes Malaysian laws.
"Any student found to be participating in such gathering/activity or who is arrested by authorities for doing so may be subjected to disciplinary proceedings," said the Monash University registrar Susheela Nair in the email.
