Police investigating the robbery of a pub in Sydney’s south-west last year have released CCTV of the incident.

Around 10.20pm on Thursday 1 October 2015, two armed men – both with their faces concealed – walked into a pub on Howard Road, Padstow.

One of the men approached a security guard from behind and punched him in the head, knocking the guard unconscious.

The men – one of whom was armed with a machete, the other with a tomahawk – subsequently demanded cash from bar staff. After being given an amount of money, they fled the scene.

Emergency services were called to the location, and ambulance paramedics transported the security guard to hospital for treatment of a suspected broken jaw and concussion.

Police spoke to staff members and the 15 or so customers who had been inside the pub at the time of the armed robbery.

The incident is being investigated by police from State Crime Command’s Robbery and Serious Crime Squad.

Police have released CCTV of the incident, in the hope someone can assist with identifying those responsible.
