Police are keeping tight-lipped about the arrest of two people at an orientation concert last night.
They've confirmed seven people were evicted from the concert, and two were arrested.
But they won't say whether those arrested were male or female, or university students.
Police also won't disclose their ages, or what they were arrested for.
It comes after the recent arrest of a university student for possessing the class B drug known as ecstasy.
Last night's concert was attended by about two and a half thousand people.
All available police are rostered on this weekend, for the end of orientation, coinciding with two major sports events.
