Opposition UPND Lusaka Province Spokesman Gilbert Liswaniso is still locked up in Woodlands Police cells almost a week since he was arrested.
Mr. Liswaniso was picked from UNZA Radio where he was featuring on a Special program called the Lusaka Star earlier this week.
It is alleged that Mr. Liswaniso issued disparaging remarks against President Edgar Lungu and has since been charged with seditious practices and inciting violence.
And UPND Lusaka Province Vice Chairman for administration Nonde Sikasote has described the continued detention of Mr Liswaniso as an act of injustice.
Mr. Sikasote believes the Patriotic Front will aim at nothing but to silence divergent views in order to remain in power forever.
