Police on the Copperbelt have warned and cautioned 30 members of staff at the Copperbelt University-CBU, among them eleven lecturers.
This is in connection with the locking up of CBU Vice Chancellor Professor Naison Ngoma, in his office last week.
Copperbelt Province Police Chief Charity Katanga has confirmed the development to ZNBC News in a telephone interview in Kitwe.
Ms. Katanga disclosed that the CBU lecturers and other support staff have been charged with unlawful confinement, contrary to the laws of Zambia.
She also disclosed that investigations into the matter have continued.
And CBU Academic Union Deputy Secretary General Kabaso Musonda confirmed to ZNBC News that some lecturers and support staff received police summons on Monday and Tuesday to appear at Riverside Police Station.

He also said eight members of the executive have left for Lusaka where they are expected to meet Minister of Labour and Social Security Joyce Nonde over the impasse between the lecturers and Professor Ngoma.
Dr. Musonda said his members appeared before the police for questioning over their role in events leading to the protest and subsequent locking up of the Vice Chancellor.
