Whittlesea Crime Investigation Unit detectives are appealing for public assistance following an aggravated burglary in Lalor last week.
Investigators have been told two unknown males smashed their way into the front bedroom of a residence on Dalton Road about 3am on Friday 5 December.
Once inside, the offenders threatened the female occupant with a knife before stealing a bag containing the victim's wallet as well as several presents underneath a Christmas tree inside the home.
There were no physical injuries.
The offenders smashed the victim's car window and slashed the vehicle's tyre before fleeing.
At this stage investigators are treating this as a targeted incident.
Investigators have released CCTV and images of two men they believe can assist with their enquiries.
The offenders are described as aged in their 20s and were wearing ??-coloured hooded jumpers, trackpants, balaclavas and carrying backpacks.
Anyone who witnessed the incident, has dashcam or CCTV footage or anyone with information is urged to contact Crime Stoppers on 1800 333 000 or submit an online confidential report at www.crimestoppersvic.com.au.
