A close relative of slain Bhisho official Sakhekile Ndudula was arrested for his murder at the weekend.
This comes after detectives allegedly uncovered what they believe is gunshot residue on the clothes the 44-year-old woman was wearing on the morning of his murder.
Police also believe that the crime scene was tampered with.
When police forensic officers arrived at the Cambridge West home of Social Development MEC Nancy Sihlwayi’s chief of staff, Ndudula, to try to piece together the murder puzzle, they allegedly found that blood had been wiped off the floor and wall.
“This is what caused her [relative] to be arrested on Friday,” a senior police officer, who is close to the investigation, said.
The woman cannot be named until she appears in court.
Ndudula was shot eight times on the morning of September 14.
He had allegedly been quizzed by the Hawks a few days before his murder – in regard to another investigation involving the department. This is what led the Eastern Cape Hawks to initially take over the investigation, as they believed it had been a political hit.
However, in the days following the murder, and as more evidence emerged, the Hawks handed the investigation back to police investigators in Cambridge. The murder weapon has not been found. A tenant who stays in the backyard of the Ndudulas’ home, reported having seen Ndudula leaning against his vehicle in the driveway covered in blood.
His wife took him to hospital, where he was declared dead.
It had initially been thought that he was assassinated by unknown gunmen as he prepared to leave for work.
Cambridge police station commander Brigadier Nomso Siganga praised the investigating team for the arrest.
“I am happy with the latest developments in this case,” Siganga said.
Provincial social development spokesman Mzukisi Solani said: “Now it is up to the court to test the validity of any evidence available.
“Ndudula’s death sent shock waves in and outside of government.”
