Westgate Divisional Response Unit are investigating after shots were fired into the bedroom of a home in Werribee earlier this month.
It is believed three offenders wearing dark-coloured clothing exited a silver sedan outside a Powlett Street property on Friday, September 5, about 9.10pm.
The trio approached the property, allegedly firing multiple shots into the front window before fleeing.
A 23-year-old man, who was asleep in the front bedroom at the time, was lucky to escape injury.
Five other occupants in the home, ranging in age from 14 to 51 years of age, were not injured.
Investigators are looking into whether a teenage occupant of the property was the target of the incident.
