Police broke-up the demonstration just as the UPND youths tried to join into Addis Ababa Drive from their party headquarters situated on Lagos road in Rhodespark.
The police who fought running battles with the UPND youths managed to apprehend some of the protesting youths who have since been detained.
QFM staffer Alexander Musokotwane who went to cover the demonstration was also beaten up be Police officers despite having an identity card.
Traffic on Addis Ababa drive was temporarily interrupted as the Police tried to restore order.
The UPND had vowed to defy a ban by the provincial police command not to go ahead with the demonstration.
The UPND and other opposition political parties are calling for resignation of the DPP over the K14 billion debt owed by the defunct Zambian Airways to the Development Bank of Zambia in which he was one of the Directors.
And Lusaka province Police commissioner Charity Katanga who led the police operation said Police will not allow lawlessness to take place in the country.
Ms. Katanga has further dismissed claims that the decision by police to stop the UPND demonstration was politically motivated.
She says the UPND was supposed to follow the correct procedure in airing out their views to the public.
