The Hawks confirmed that they were investigating African National Congress Youth League president Julius Malema for fraud and corruption, eNews reported on Saturday. 'From the information that we have, we have enough to tell us that we need to do a full investigation...there's a lot that tells us that we have reason to worry,' Hawks spokesperson McIntosh Polela said. ENews also reported that the South African Revenue Service (Sars) initiated its own investigation into Malema's financial affairs and alleged failure to pay tax.
