The incident happened after two women, aged in their 20s, got off a train at the Albion Railway Station on Thursday 30 March about 11.25pm.

As they walked from the station they were followed by two other women who had been traveling on the same train.

After leaving the station the victims walked to nearby St Albans Road when they were approached by the two women.

The two women demanded that the victims hand over their money or they would be stabbed with a syringe.

The two victims ran from the scene without handing over any belongings.

Investigators have released CCTV images of two women they believe may be able to assist with their enquiries.
