Yarra Crime Investigation Unit detectives have arrested three people following criminal damage in Mooroolbark and a stabbing in Kilsyth on Thursday 23 November.
The group attended a property on Taylor Road in Mooroolbark where they smashed several windows at the front of a home about 1am on 22 November.
A 70-year-old man and a 73-year-old woman were home at the time but were not injured.
The group then fled the scene before attending another property on Durham Road, smashing several windows at the front of the home about 1.20am.
The resident, a 19-year-old man, confronted the group who chased him back inside the house before attacking him.
He sustained non-life-threatening injuries and was taken to hospital for treatment.
A 19-year-old woman who was also home at the time was not injured, but two of the offending males sustained minor injuries.
The group then left the scene in a white 2001 Ford sedan.
The driver of the sedan later dropped off two of the offenders, a 19-year-old Heathmont man and a 20-year-old Box Hill man, at a hospital in Maroondah.
They have now been arrested and are assisting police with their enquiries.
The driver of the sedan, a 19-year-old Dixons Creek man, was located on the Maroondah Highway in Chirnside Park and arrested at the scene about 4am.
All three offenders are now assisting police with their enquiries.
Early indications suggest the criminal damage in Mooroolbark was a case of mistaken identity.
However, it is believed the parties are known to each other for the stabbing in Kilsyth.
Anyone who witnessed the incident or has information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppersvic.com.au.
