A man who allegedly entered the Melbourne headquarters of the Australian Border Force with two guns, was not a client, the federal government says.
The 38-year-old man was arrested at the Docklands building about 1.30pm on Monday and police say they seized guns, ammunition and drug paraphernalia.
Home Affairs Minister Peter Dutton said the man is not a client of the Australian Border Force.
"On the advice available to me, a person that wasn't a client of the Australian Border Force entered into the foyer of the ABF facility there, and there was an incident then that the Victorian police responded to," Mr Dutton told reporters in Melbourne on Tuesday.
"As I understand it, the person was taken into custody and charges have been laid against that person. I will let Victorian Police comment on it further."
The man, of no fixed address, was remanded in custody overnight to appear in the Melbourne Magistrates Court on Tuesday.
He is charged with two counts of possessing firearms, criminal damage, assault police, resist arrest, aggravated burglary and reckless conduct endangering serious injury.
