Police are urging residents of Tasbet Park in Witbank, Mpumalanga, to "get involved in the fight against crime" as hijackings in the suburb become increasingly violent.
Captain Eddie Hall , spokesman for the Witbank police, has asked locals to report any suspicious-looking people or vehicles in the area.
"Residents mustn't wait for crime to be committed but they should work hand-in-hand with the police."
He said he was disappointed with the local residents because when the police organised a meeting to discuss the crime "only two people turned up".
During the past three months there have been 10 hijackings in Tasbet Park Extensions 3 and 4.
Last Friday evening in Extension 2 two people were shot dead in the driveway of a house.
"A man was being collected by a friend. They were going away for the weekend.
"The friends were attacked by three men who shot and killed the driver and his companion before driving off in a silver grey Toyota Yaris at about 7.30pm. The registration of the vehicle is DGV 379 MP," he said.
"Police are in possession of the identities of the dead men but we will only allow their names to published once their next of kin have positively identified them."
Meanwhile, a report from the Highveld area police at Kwa-Mhlanga stated that there were three occupants in the car.
The Tasbet Park resident was shot dead as he opened the gate and the other two in the car heard him screaming for help.
"His companion jumped out of the vehicle and rushed towards his screaming friend. He was also shot and both died at the scene.
"The hijackers then forced the dead men's female companion out of the vehicle at gunpoint before driving off in the car," said a police spokesman.
