The Hawks reportedly arrested Motaung, along with a Mpumalanga businessman, on Wednesday in connection with the controversial construction of the R1.2 billion Mbombela Stadium in Nelspruit. The venue was built for the 2010 Soccer World Cup.
"The club has not received any formal confirmation of Bobby Motaung's arrest and therefore cannot comment on the matter at this time," a statement on Chiefs' official website read.
Hawks spokesperson McIntosh Polela said on Wednesday: "We have arrested two men on allegations of fraud, forgery and theft in relation to the Mbombela Stadium construction. I can confirm one man was arrested in Naturena and another in Cape Town. We are looking for a third person."
He then added: "This is the conclusion of the first phase of investigations into tenders in Mpumalanga. There may be more arrests."
