The Special Investigating Unit has frozen the bank accounts of seven more companies, over the R431-million Gauteng school sanitising tender. This is in addition to the more than 40-million rand preservation order granted last month, which saw the accounts of 14 companies frozen. It's understood some of the companies are not even in the cleaning business. SIU Spokesperson, Kaizer Kganyago says 6 of those companies belong to one person. He spoke to Dan Moyane earlier.
