Corruption commission officers raided Parliament House in Canberra on Thursday as part of an ongoing investigation targeting a subject that has not been made public.
A media officer for the National Anti-Corruption Commission said in an emailed statement that its officers were in the building on Thursday.
“The commission can confirm it carried out operational activity today at Parliament House,” the officer said on Thursday evening.
“This was in relation to an ongoing investigation.”
“The commission can confirm that the investigation does not relate to a current or former parliamentarian.
“As the matter is ongoing, we will not be making further comment, as to do so may compromise operational activities or unfairly impact reputations,” the officer said.
As well as MPs, the commission can investigate their staff, public servants and government contractors.
The Parliamentary Library estimates about 5000 people work in Parliament House during peak periods.
The commission began operating last year. It currently has 32 preliminary investigations and 29 corruption investigations underway, with six cases before courts.
