An aged care facility in Melbourne's north-west remains under police protection, after a shooting outside the building last week.
Police say two males were seen outside the Arcare residence in Maidstone in the early hours last Friday, when 10 shots were fired.
Arcare has increased security at its Victorian and interstate sites, as police continue to investigate the incident.
A chain of aged care facilities has increased its security across the country, after shots were fired at one of its residences in Melbourne's inner north-west last week.
Police were called to Arcare Aged Care on Hampstead Road in Maidstone just before 4:30am last Friday, after two males dressed in black were seen exiting a white SUV.
Police said approximately 10 shots were fired, with one bullet hitting the building, before the pair fled the scene in the vehicle.
In a letter sent to residents and families, Arcare said was working closely with Victoria Police as the shooting was investigated.
"Arcare has taken proactive steps to increase security at our Victorian and interstate site," it said.
Arcare said it had increased wellbeing support for its residents, visitors and team members.
The company operates over 60 aged care facilities around Australia, in Victoria, New South Wales, Queensland, the ACT and South Australia.
