Yarra Ranges Crime Investigation Unit detectives are investigating after an altercation in Warburton last night left four people injured.
Police have been told the altercation broke out at a property on Comangin Avenue on Tuesday 4 April about 7pm.
Three men, two aged 29 from Millgrove and a 49-year-old from Yarra Junction, and a woman aged 37 from Warburton; were located in the vicinity of the property with suspected non-life threatening stab wounds and taken to hospital for treatment.
A 36-year-old man from Warburton was arrested in relation to the incident and is currently assisting police with their enquiries.
It's believed those involved are known to one another and the altercation may relate to an incident earlier in the day in which a car was damaged at Wesburn.
