Two former employees of engineering firm Asea Brown Boveri have been arrested along with their wives in connection with an allegedly inflated multimillion-rand contract for work at Eskom’s Kusile power station. It is alleged that they received cash and cars from a company ABB sub-contracted, called Impulse International. The Investigating Directorate arrested the four people as part of a multi-agency initiative involving the Hawks and SARS in Durban, KwaZulu-Natal and Middelburg in Mpumalanga after raiding their premises. Former acting Eskom CEO Matshela Koko was accused of promising ABB R6.5-billion in future contracts if it sub-contracted work on Kusile to Impulse International, a company partially owned by his stepdaughter, Koketso Choma.
