ANC Members Oppose Bail
Police men with their police cars
Fifteen police vehicles, including several nyalas formed a U-shape around the entrance to the court.
African National Congress members outside the police line held up posters of Chika and placards denouncing the eight, especially local government MEC China Dodovu.
"Hands off to our comrades hands on to the killers of Chika. Justice must prevail," one of the placards read.
Another read: "ANC is under attack Gwede [Mantashe, ANC secretary-general] save it. No bail for China".
Earlier, the court heard the State was opposing bail. Prosecutor Riekie Krause said if the men were released, local residents would be shocked and outraged. Several of them had also failed to disclose previous criminal convictions or pending cases, she told the court.
Chika, 33, was shot point-blank range in the driveway of his Klerksdorp home on December 14. He died in a local hospital.
"The State has a strong case against the applicant [Dodovu]," Krause said.
She said he had three passports: a diplomatic one and two personal ones.
Another accused, Sihlangu Sekhakhane, had previously confessed to the crime. He had also led police to his gun, Krause submitted. She said forensics had later matched the bullets which killed Chika to this gun.
The other six accused are community member Jeffrey Letuka, North West provincial ANC Youth League chairman Papiki Baboile, ward secretary Paul Molomonyane, councillor Itumeleng Molebatsi, municipal worker William Malefo, and taxi driver Kgotso Kali.
The court heard that Sekhakhane had claimed to have met Kali in a BMW X5 shortly before the crime.
Kali allegedly told him that, before he could attend the African National Congress's conference in Mangaung, in December, Chika had to be killed.
Krause confirmed that Baboile owned a BMW X5.
She told the court an unnamed witness had confirmed to the State that some of the eight had previously discussed murdering Chika during a meeting. Krause said bail was also being opposed because some of the applicants knew "witness X".
