He has since been charged with multiple offences including home invasion, use of a firearm and three counts of criminal damage by fire.
The charges follow two separate incidents at a home belonging to underworld figure Mohammed Charif in Fawkner.
The first occurred about 11pm on December 23, when two male offenders attended the home in an alleged stolen white Suzuki Swift.
Police were told one of the men fired shots at the front door, while the other man armed with a firearm attempted to force entry into the home, but was unsuccessful.
The two men fled the scene in the Suzuki Swift.
Three people were inside the home but were not physically injured.
Police said the stolen car was found burnt out with a firearm inside on Fashion Parade in Broadmeadows.
The second incident occurred about 3.20am on December 28 when emergency services were called to reports of a vehicle fire on Major Road.
Police will allege a group of offenders ran from a vehicle, pouring accelerant into the driveway of the home, before setting a blue Toyota Camry parked in the driveway alight.
They then fled the scene in a waiting vehicle.
A short time later another car was found on fire about 1km away at the intersection of William and Lowson Streets.
Police believe both incidents were targeted and the investigation remains ongoing.
The 20-year-old was remanded to appear at Melbourne Magistrates’ Court on May 27.
