A Dandenong North man disturbed two burglars who were searching his home for keys.
The 36-year-old returned to his Howe Avenue home about 11.40am on Wednesday 4 May and found the men inside.
They fled with two sets of car keys and a set of house keys.
On Friday Operation Cosmas investigators released an image of a man they believe could help them to solve the crime.
Cosmas involves police from across the southern metropolitan region and is aimed at combating a rise in burglaries and car-jackings.
Investigators urged anyone who recognised the man in the facial composite to call Crime Stoppers on 1800 333 000 or make a confidential report at www.crimestoppersvic.com.au.
