Investigations are ramping up into an armed hold up at an antique shop in Mayfield last month.
CCTV has been released which depicts a man threatening a female employee of the Maitland Road business with a gun and a machete around 4.45pm on May 18.
The man allegedly fled with cash and jewellery, while the staff member escaped physical injury and called police.
A crime scene was established and examined by forensic specialists.
As inquiries continue, officers are trying to identify the man in the security tape.
He is described as 180cm tall with a solid build, and was wearing blue overalls, a fluorescent yellow vest and a black, full-faced motorbike helmet as well as black and yellow gloves at the time.
Anyone with information is urged to contact Crime Stoppers.
