Brimbank Crime Investigation Unit detectives continue to investigate a stabbing which occurred in Sunshine North on Tuesday 11 April.
Investigators have been told a man and a woman entered a takeaway business on Furlong Road about 7pm.
The woman ordered and paid for food before waiting near the store entrance with the man.
The woman collected the food at the counter and the man reached over and slashed the female attendant across the face with an edged weapon.
The victim, a 45-year-old St Albans woman, was taken to hospital with minor facial injuries.
The pair fled the scene and were last seen in a vehicle headed north along Godfrey Avenue.
Both the woman and offender had their faces covered with black masks and they were wearing hoodies with the hood covering their head.
Investigators obtained further images of a man with a tattoo who may be able to assist police with their enquires and are releasing that image along with the originally released images.
Anyone who witnessed the incident or information is urged to contact Crime Stoppers on 1800 333 000 or make a confidential report at www.crimestoppersvic.com.au.
