A weapon is believed to have been used in the suspected murder of a man found dead near Melbourne's Monash University.
A woman on the way to work found the man's body face-down in a garden area of a Notting Hill apartment block on Friday morning.
Homicide detectives say they are yet to formally identify the Asian man, believed to be in his late 20s or early 30s.
They're still unsure exactly how long his body was lying in the garden area before being discovered near a staircase about 9.30am.
"At this stage we don't know how he was assaulted and we won't have those details until the post-mortem is conducted," Detective Senior Sergeant Stephen McIntyre told reporters on Friday.
