Jakarta – The National Commission of Human Rights has found 15 rubber bullets at the National University (Unas) campus in East Jakarta, where a clash between police and students took place last month.

"The bullets are round in shape and black in color, like big marbles. There is some kind of metal inside the rubber," said commission member Nhur Kholis on Wednesday, as quoted by tempointeraktif.com.

He was part of a special team established by the commission to investigate the incident. He reported the finding to the Jakarta Police on Wednesday.

Nur cited city police chief Insp. Gen. Adang Firman as saying the rubber bullets were not the standard type the Indonesian police use.
