Mandevu MP Jean Kapata and Munali’s Mumbi Phiri have been discharged from hospital and taken back to Lusaka central police cells.
The two are among the nine people who were arrested last Friday for honking in protest against the acquittal of former president Fredrick Chiluba.
The seven others were released after paying admission of guilty fees. But the two were denied police bond as they are to face another charge of harassing police officers.
Police say a medical doctor will have to certify the two PF MPs fit to stand trial before they can go to court. They will have to remain in custody.
Meanwhile, the forum of political parties that went to protest at the British High Commission failed to deliver the petition to High Commissioner Thomas Carter.
The petitioners had no choice but to leave the petition with a guard at the entrance of the building which was heavily guarded.
Forum spokesperson Edwin Sakala later told journalists that Carter will have to respond to the petition which he hoped the guard will deliver.
