Three people of interest have been identified in the murder case of Madlanga commission witness Marius van der Merwe, and one has been taken in for questioning, says national police commissioner Gen Fannie Masemola.
Van der Merwe was gunned down when he arrived at his Brakpan home on Friday evening.
He gave crucial evidence at the commission in November, claiming Ekurhuleni metro police EMPD deputy chief Julius Mkhwanazi had ordered him to dump the body of a man officers had killed during an interrogation involving tubing.
