Police are investigating the suspected stabbing death of a man in Melbourne's south-east.
Emergency services were called after a man with suspected stab wounds was found on the corner of Leonard and Beach streets in Frankston at about 1:20am today.
After efforts to revive him, including CPR, the man, who is yet to be formally identified, was declared dead at the scene.
Homicide detectives are probing a potential connection between the man's death and an earlier incident at a property in Lucerne Crescent.
They have set up crime scenes at both locations.
A woman was arrested at the scene of the man's death in relation to another matter.
Police allege the people involved were known to each other.
Anyone with information that may assist the investigation is urged to contact Crime Stoppers on 1800 333 000 or online.
