UNITED Party for National Development (UPND) secretary general, Winston Chibwe and more than 70 party youths have petitioned the Lusaka High Court to order the Zambia Police Service to release medical reports to five youths allegedly injured during a demonstration.

UPND members, Aaron Pumulo, 35; Joseph Mazonda, 48; Lemmy Mukoba, 29; Patrick Ntalasha, 28, and Newton Chisuntu, 30, are in court charged with idle and disorderly conduct likely to cause breach of peace.

They are alleged to have committed the offence on June 6, this year.

The youths also want the court to declare that the action by former Lusaka Province police chief, Charity Katanga to stop them from carrying out a lawful and peaceful demonstration was a violation of their Constitutional rights.

In a petition filed before the Lusaka High Court Principal Registry on Thursday, the cadres felt that Ms Katanga and Attorney-General, Mumba Malila, should compensate them general and exemplary damages for assault and grievous bodily harm.

The youths are also demanding K2.2 million belonging to one of the injured cadres, Pumulo, which was allegedly stolen by one of the police officers during the fracas.

The youths who have sued Mr Malila and Ms Katanga as first and second respondents, respectively, contend that on May 29, this year, they, in accordance with the regulations relating to public meetings forwarded a notice to Ms Katanga informing her of the intentions of the party youths to hold a peaceful demonstration on June 6 2012 in support of an independent Judiciary.

They contended that during the process, the police "ruthlessly and mercilessly" attacked them with short batons and other weapons.
