Two South Africans who lost relatives in the Synagogue church building collapse intend to sue Prophet TB Joshua of Synagogue Church of All Nations, SCOAN. According to the BBC, the two men, who both lost sisters in the collapse, are calling on more families to come together in bringing a case against the preacher.
At least 115 people, including 84 South Africans, died when the multi-storey building fell down on 12 September.
The authorities say it had more floors than its foundation could hold.
On Sunday, Joshua announced plans to travel to South Africa to visit the families of the deceased.
Thanduxolo Doro and Mpho Molebatsi waited at Johannesburg's OR Tambo airport for days after the collapse for news of their sisters, who had been visiting SCOAN.
Both families had last heard from their relatives hours before the collapse.
"It is not that the building collapsed, rather what was done after the collapse - we didn't get any news from the church," Doro, whose sister Vathiswa Madikiza died, told the BBC.
"When I contacted them they wouldn't tell me anything. We saw reports that emergency workers were denied access initially, access that could have saved lives. The actions of the church after the incident are very telling," he said.
