Naidu said the man had since been connected to a gang-related shooting in Melkbos Street in West End, Bethelsdorp, on Tuesday.
“Two people were walking in the street and he allegedly opened fire at them, No one was injured but a case was opened,” she said.
Naidu said the revolver was linked to the 169 firearms missing from East Cape Gun Traders, a gun shop owned by Anthony Lombard, 79, which is run from his house in Charlo.
Lombard is under criminal investigation after police found 169 guns missing from the store’s vault during an inspection sparked from a police shoot-out.
In January, police shut the shop down and confiscated 359 guns belonging to the company and private owners who had booked their weapons in.
The suspects are expected to appear in the Port Elizabeth Magistrate’s Court on Friday and Monday.
