Former Ekurhuleni Employee Relations Director Xolani Nciza says a letter issued by Brigadier Julius Mkhwanazi was a serious abuse of authority.
Testifying at the Madlanga Commission in Pretoria, Nciza revealed that the letter - addressed to whom it may concern - could have allowed private individuals linked to businessman and crime suspect Vusimuzi Cat Matlala, to evade police checks.
He warned that the document may have enabled Cat VIP vehicles to pose as official Metro Police units, undermining accountability within the department.
