Police have arrested a man after he was found carrying a firearm onto the Aristotle University of Thessaloniki campus.

The man, whose details have not been made public, was arrested late Wednesday after police searched a group of ten people that were “moving suspiciously” on the campus.

The gun was sent for ballistic tests to determine if it had been used for any crimes.

Officials also arrested a 25-year-old man for not having legal residence documents.

No more details were made available.
