Police Spokesperson Elizabeth Kanjela has said the 31 UNZA students who were apprehended on Friday have been released.
She said after screening them, 25 were students from UNZA while the remaining 12 were ordinary citizens caught up in the fracas.
The students have since paid admission of guilt fees.
And Ms Kanjela said the situation at UNZA has normalised and has implored students not to take the law in their own hands.
She also refuted claims by some students that the hostel which caught fire when students rioted was caused by a canister.
She said the Police have called on experts to determine the cause of the fire.
Meanwhile, the Copperbelt University (CBU) in Kitwe maintained peace over the weekend with students conducting themselves in an orderly manner despite last Friday’s class boycott to their grievances over alleged poor handling of the economy by Government.
A check around the campus over the weekend found peace and order prevailing at the second highest learning institution in the country.
Copperbelt University Students Union (COBUSU) president Oscar Mbewe said in an interview that the university experienced peace and order during the weekend as the students did not engage in any disorderly conduct.
“The weekend was incident free. We didn’t witness any form of unruly conduct and behavior among the students,” he said.
Mr Mbewe, however, said the students were scheduled to hold their meeting later in the evening at which a position was expected to be made on their next course of action following the Friday’s class boycott, which they termed ‘National Holiday’.
