The Medan police have arrested three students they accuse of involvement in the killing of a 21-year-old man during a brawl that broke out between students of Huria Kristen Batak Protestan (HKBP) Nommensen University in Medan, North Sumatra on Friday.

Medan Police chief Sr. Comr Dadang Hartanto said the three students were named suspects because they had allegedly brandished sharp weapons during the melee.
