A toddler and his grandmother are in a stable condition after they were shot during an armed robbery at Randridge Mall, Gauteng police said on Sunday.

Another bystander and a police officer were also injured in Saturday's robbery.

“Three victims' condition have been described as stable at hospital,” said police spokesman Lt-Col Lungelo Dlamini.

The elderly woman and her grandson were shot in the leg. The fourth victim, a man, was treated at the scene for a flesh-wound on the side of his stomach.

A nine-man gang entered a jewellery store at the mall and held staff and customers at gunpoint.

They fled with jewellery in a bakkie.

Four men were arrested after a high speed chase with police. Five escaped and were being sought by police.

The four are due to appear in the Randburg Magistrate's Court on Monday. - Sapa
