A video clip appears to show a South Korean pastor physically abusing church members and coercing them to beat each other, footage that emerged amid an investigation into claims that the woman was the leader of a religious cult in Fiji, the Guardian reports. Footage reviewed by the Guardian and South Korean police reportedly shows Shin Ok-ju, pastor of the messianic South Korean Grace Road Church, subjecting her followers to abuse such as hair pulling and cutting during her sermons in South Korea. The footage was originally aired as part of a documentary program by a South Korean broadcaster, the Guardian reports. Some followers were reportedly forced to endure “ritual beatings” at designated areas called “threshing floors” at the religious group’s compound in Fiji.
