Prosecutors say Lee Man-hee conspired with other sect leaders to withhold information from authorities during the peak of the outbreak among his more than 200,000 followers.
South Korean authorities have arrested the founder of a secretive Christian sect at the centre of the country's largest outbreak of Covid-19 infections on Saturday for allegedly hiding crucial information from contact-tracers and other offences.
Lee Man-hee is the powerful head of the Shincheonji Church of Jesus which is linked to more than 5,200 of South Korea’s 14,336 Covid-19 cases.
Its branch in the southern city of Daegu emerged as the biggest cluster after infections spiked in late February.
Health authorities used an aggressive test-and-quarantine program to contain the outbreak in Daegu and nearby towns by April, but the country has seen a resurgence of the virus in the Seoul metropolitan area since late May.
Black-out over outbreak
Prosecutors allege the 89-year-old conspired with other sect leaders to withhold information from authorities during the peak of the outbreak among his more than 200,000 followers.
Lee, who has described the novel coronavirus as the "devil’s deed" to stop the sect's growth, allegedly hid details on members and their meeting places as authorities tried to trace infection routes in February, Yonhap news agency reported.
Lee is also suspected of embezzling about $4.7 million (5.6 billion won) in church funds, including about 5 billion won which he allegedly used to build a retreat, Yonhap said.
The sect said in a statement that Lee was concerned about government demands for members' personal information but never tried to hide anything.
Lee was arrested immediately after a court in Suwon District, south of Seoul, approved the warrant.
A prosecution official could not be reached outside of office hours.
