Last weekend Sunday World reported that the Hawks were investigating the charismatic preacher, after members of the church leadership claimed he was sending an estimated R15-million a month to Malawi, his country of birth. The money is allegedly transported in Bushiri's private jet and other vehicles.
Hawks spokesman Hangwani Mulaudzi was quoted as confirming they have launched a money-laundering probe into the prophet, known as the "Major One", but did not confirm the amounts.
Mulaudzi told the newspaper that the investigation was still in its "infancy stage".
The church rejected the report as "a figment of the imagination of the authors".
"We are not ignorant of the clandestine moves by some groups and individuals but we take solace in the established fact, which says that, no matter how far falsehood travels, it would eventually be overtaken by truth," the church said.
"We are committed to working with any government agency who so wish to look at our books."
