A 26-year-old female store attendant was working in the Gladstone Avenue shop when a male approached the counter about 8.15pm and threatened her with a knife.

The woman later told police the male jumped the counter and demanded money from her.

She handed him cash and cigarettes and he ran out of the shop.

The woman, injured in the robbery, contacted police.

Officers attended the shop and set up a crime scene.

The area was later examined by specialist forensic officers.
