Police have released CCTV images of three people they believe can assist with inquiries following a robbery in Sydney’s south-west last year.

Just after midnight on Tuesday 24 October 2017, three men entered a service station on the intersection of Elizabeth Drive and Meadows Road, Mount Pritchard.

The men approached the counter and threatened the employee before assaulting him and fleeing the scene with cash, cigarettes and a number of personal items belonging to the employee.

The group was last seen running down the alley of Meadows and Rose Street.

Officers attached to Fairfield City Police Area Command have commenced an investigation and would like to speak to the three people depicted in the images who might be able to assist with their inquiries.

The men have been described as being of Pacific Islander/Maori appearance, early to mid 20s, and of medium build.

The first person is shown wearing dark pants and a blue hooded puff jacket with a red zipper.

The second person is shown wearing grey track pants and a dark blue hooded jacket with two white stripes running down the sleeve.

The third person is shown wearing dark pants and a maroon jacket with a black hood and sleeves.

Anyone with information that may assist investigators is urged to come forward.

Inquiries are continuing.
