Casey Crime Investigation Unit detectives are appealing for witnesses after a man was assaulted during an aggravated home invasion in Cranbourne North last night.
It's believed three male offenders attended a Lindenow Court address and ransacked a bedroom about 7.15pm.
A neighbour heard an occupant scream and jumped the back fence to assist when he was confronted by the offenders.
One offender struck the victim to the head with an unknown weapon before the group fled on foot.
The 41-year-old man was transported to hospital with non-life-threatening injuries.
The occupants of the address were not injured.
Police are investigating whether the burglary was targeted, and it remains ongoing.
Anyone who witnessed the incident or with information is urged to contact Crime Stoppers on 1800 333 000 or file a confidential report online at www.crimestoppersvic.com.au
