The police arrested 13 students from the Jayapura University of Science and Technology (USTJ) who raised the Morning Star flag during a demonstration at the local campus in Padang Bulan, Jayapura.

Jayapura Police Chief Kombes Victor Mackbon said that apart from raising the Morning Star flag, the dozens of students with the help of their colleagues carried out anarchic acts and threw stones at officers when the action was about to be dispersed.

In fact, the police were forced to fire tear gas to disperse the student anarchist action.

"Four police personnel were injured in the incident, so they were immediately ordered to receive an autopsy," said Kombes Mackbon quoted by ANTARA, Thursday, November 10.

The Kapolresta has yet to confirm the status of the 13 students who were secured, whether they are pure USTJ students or not. "Investigators are still examining the 13 students," he added.

Separately, USTJ Deputy Chancellor for Student Affairs Isak Rumbarar acknowledged that there were students who were secured at the Jayapura City Police.

"I can't say for sure whether they are all USTJ students or not because currently they are still being handled by the Jayapura City Police," said Isak.

Isak admitted that he was shocked when he learned that the demonstration by students on his campus was accompanied by the raising of the Morning Star flag, prompting the security forces to act according to applicable law.

According to him, USTJ provides space for students to express their aspirations, but student actions that violate the law by raising the Morning Star flag cannot be justified.

"There was an pelting action by a group of students and the police fired tear gas," explained Isak Rumbarar.
