Police are appealing for information following an alleged armed robbery in Port Kembla yesterday.

About 10.15pm (Thursday 12 September 2013), a 61-year-old man was working in a service station on Church Street, when two men entered the store, armed with a knife and a black firearm.

The man holding the firearm allegedly demanded money and cigarettes from the man.

The man handed over a quantity of cash and cigarettes and the men fled the scene, heading east on Church Street, towards Wentworth Street.

Police were called and a crime scene was established.

Both men are described as being of thin build, 20-25 years old and approximately 166cm tall.

One man was wearing a black hooded jumper, blue long pants, white runners with two black stripes, a yellow and light brown baseball cap under his hood, maroon-coloured material covering his mouth and nose, and he was carrying a black sports bag.

The second man was seen wearing a black hooded jumper, grey pants, grey walking shoes with white rimed soles, white-coloured material covering his mouth and nose, and a black baseball cap.
