ACT Policing arrested a 23-year-old Oxley man after a search warrant was executed at his home early this morning.
Around 6.30am, members of Specialist Response and Security commenced negotiations with the resident of the house in an attempt to have him safely exit.
The man complied with the request, exiting the house as members of Criminal Investigations executed the warrant.
During the search police located a prohibited firearm, ammunition, stolen property and methamphetamine.
The man has been conveyed to the ACT Watch House and will face the ACT Magistrates Court this afternoon.
