Woman slashed at Port Melbourne unit

A woman who came out of her Port Melbourne unit to tell a yelling man to leave has been stabbed in the back of the head.

Police say the man was shouting outside the door of another unit at around 9.45pm on Friday and after the female occupant told him to leave he slashed at the security door with a knife.

A 30-year-old woman then came out of an adjoining flat and also told the man to leave, sparking an altercation in which she received a slash wound to the back of her head before the man ran from the scene.

She was taken to hospital with non-life threatening injuries.
