Police are investigating an attempted theft of motor vehicle in Essendon Fields last month.
Investigators believe three unknown offenders entered Wirraway Road in a stolen white Nissan Navara at about 4pm on 12 July.
The group exited the car before approaching a Black and Orange KTM Roadster motorcycle parked near Hangar 7.
Two males attempted to ignite the engine with tools while a female watched on.
A nearby passer-by observed the incident and all three offenders fled before driving away in the stolen car.
Police have released an image of a female who they believe may be able to assist with their investigation.
The female is described as being approximately 165cm tall, with a slim build and dark brown hair.
She was wearing a black Adidas jumper with yellow stripes, black tracksuit pants, and was carrying a black jacket.
Anyone who recognises the woman or with information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppervic.com.au.
