Last year during the height of the political campaigns, Mr Mwamba was arrested and charged with assaulting a street vendor and damaging his goods worth K500.
After his acquittal today, Mr Mwamba said he knew that the charges were fake.
He said all the other remaining charges he is facing are all political.
“Currently, I am facing 2 other matters in the Lusaka Magistrate Court and 1 other in the Luanshya Magistrate court. For now, all I can say is that all these matters are political and advise that we should not use state institutions to fight our battles,” Mr Mwamba said.
He added, “What is unfolding is an embarrassment to these state institutions, particularly the Zambia Police and brings in a lot of questions on the integrity and professionalism of the command.”
The UPND Vice President said there are more embarrassments to come.
