Swift response by alert police officers and security guards led to the arrest of two suspects who were caught soon after allegedly committing a robbery and hijacking at Cresta Mall in Johannesburg on Tuesday.

It is alleged the four suspects, who were driving in a white Toyota Etios, first hijacked an Opel Corsa at Cresta Mall's parking lot.

Police spokesperson Captain Kay Makhubele said the suspects also allegedly robbed a couple of their cellphones and other items.

"As the suspects were about to exit the mall, they were confronted by the police and security guards and a shootout ensued.

"One suspect was shot and injured, and was taken to hospital where he is under police guard.
