Frankston Crime Investigation Unit detectives are investigating after nine war medals were stolen during a burglary in Frankston last week.
The burglary occurred at a Margate Avenue address sometime between 5pm on 8 July and 5pm on 10 July.
The victim, a 91-year-old man, returned home and discovered it had been ransacked with nine World War 2 medals stolen, including MBE and Citation medals.
It is believed a substantial amount of cash, jewellery, an army uniform, and other items were also stolen during the incident.
Detectives also believe the offender defecated at the side of the house and used some of the stolen clothing to clean themselves.
Investigators have released images of some of the unique items in the hope someone may recognise them and come forward.
Anyone with information or who witnessed suspicious activity in the area is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report at www.crimestoppersvic.com.au
