Unitech Security walked off their jobs yesterday, leaving the gate and university unmanned.
The Unitech administration sent in a formal request (in writing) last night and police went on campus this morning.
Police are on campus not to harass, intimidate or investigate anyone but to protect government property.
There are also reports from administration that some students want to attend classes but are afraid to do so.
Lae metropolitan superintendent Anthony Wagambie Jnr says he wants peace to prevail.
