Police are still searching for the men behind a violent home invasion in Melbourne's south-east in February which left a heroic father with stab wounds and a cracked skull.
Three men, armed with a gun, a machete and an axe, allegedly stormed a Cranbourne North house on Lindenow Court about 7.15pm on February 1 and ransacked it while a man and woman were home.
Detective Senior Sergeant Kay Morgan said the men had obviously entered the home with the intention of causing harm and had made demands for money.
The woman's screams led to her neighbour, 41-year-old Russell Irwin, jumping the back fence to help her.
Senior Sergeant Morgan said two of the men then turned on Mr Irwin, a father-of-three, and attacked him with the machete and the axe.
"Russell's intervention allowed both the male and female to escape the attack without injury," she said.
Mr Iwin's skull was crushed with the axe, while he was also stabbed in his body multiple times.
The attackers then ran from the scene.
Mr Irwin, who suffered a broken skull, was taken to hospital while no one else was injured.
Senior Sergeant Morgan said police believed the offenders got to and from the scene in silver Toyota Hilux.
Police have today released CCTV footage of the car, as well as footage of an alleged offender running from the scene and images of two people they want to speak to.
Senior Sergeant Morgan said police were very close to solving the "extremely concerning" crime.
"We are desperate and committed to solving this crime," she said.
She has urged anyone who knows about it to come forward.
"There is no doubt that these offenders would have told someone close to them about what they did."
Senior Sergeant Morgan said the attack was thought to have been targeted because the men had demanded money, but a connection between them and the victims had not been confirmed.
Anyone who can identify the car or identify the images is urged to contact Crime Stoppers on 1800 333 000 or file a confidential report online at www.crimestoppersvic.com.au
