KwaZulu-Natal police are searching for the killers of a taxi driver who was shot and stabbed in cold blood in Pietermaritzburg on Saturday
Forty-seven-year-old Moses Ngcobo was found dead in his mini-bus taxi in Westgate, not far from his home.
Police said they were following leads, but no arrests had been made at this stage.
A search for his killers had been launched immediately.
Taxi bosses in the area were unavailable to comment on whether the killing was industry-related.
Police spokesman Henry Budhram yesterday said the motive for the killing had not yet been established, but they were not ruling out the possibility that it might be related to taxi violence.
"It has not been established whether the motive was robbery, but we are definitely not ruling out the possibility that the killing was related to taxi violence," he said.
He said investigations were exploring all possibilities.
Ngcobo was found dead in his mini-bus taxi in Westgate, having sustained a single gunshot wound to the head and incurring several stab wounds to his body.
Police had received a call in what looked like a car accident, but on arrival found that the deceased had actually lost control of his vehicle when he was shot and stabbed while behind the wheel.
Further investigations revealed that prior to the incident, the victim had been transporting nurses from Edendale Hospital to their homes.
It looks like Ngcobo, of Westgate, was probably on his way home after delivering the nurses when he was attacked.
