Gun, machete in SA petrol station fight

Police are investigating an altercation between two people at an Adelaide petrol station.

It's believed a gun was fired during the incident on November 8, in which a machete was also being wielded.

"It is of great concern to police that a firearm may be in our community and in the hands of someone who may use it so recklessly," Detective Chief Inspector Wayne Overmeyer said on Thursday.
