A man received a stab wound to his right hand during an argument on Scott Street, Dandenong.
Police said the 27-year-old from Rowville was walking outside the New Hotel with two friends about 8.40pm on Thursday 30 June.
About two to three men approached them from behind, and a verbal argument ensued.

The attackers fled the scene on foot and paramedics took the victim to Dandenong Hospital for treatment.
