Jakarta – At least six students from Mulawarman University in Samarinda were wounded in a clash with security guards when a rally against regulations on a dropout system turned ugly Thursday.

Lukas Hinuq, leader of the university's law association, said a number of university staff hurled wooden items at the students as they exited their office.

"The security guards beat me, then the university staff trampled me," Lalu Luna, another student involved in the event told tempointeraktif.com.

However, the university's spokesperson Mulyadi said the students started the scuffle by throwing stones at the security guards. The students denied these accusations.
