Police say a gang of five robbed a cellphone store in Cato Ridge on Tuesday before speeding off in a getaway car towards Umbumbulu, south of Durban.

The driver of the vehicle lost control and police caught one suspect.

Three fled into the bushes while another ran into a house and took a woman and her two young grandchildren hostage.

They were rescued after a hostage negotiator intervened.
