Officers are executing search warrants at the union's Sydney HQ
The construction union CFMEU’s Sydney office has been raided by police as part of an ongoing investigation.
Officers from the Australian Federal Police executed search warrants early on Wednesday morning at the Pyrmont-based headquarters.
Several other CFMEU offices and homes have also been raided.
An AFP spokeswoman told HRD: "A Trade Union Task Force investigation has resulted in the execution of search warrants in Sydney today.
"As this remains an ongoing investigation, no further information can be provided at this time."
NSW police are assisting with the search warrants and currently, no arrests have been made.
In a statement from the CFMEU, Dave Noonan, national construction secretary, said the union is cooperating with law enforcement.
He said: “The warrant relates to investigations under the Fair Work Act and related matters.
“The AFP have been taking an increasingly active role in industrial relations matters and have previously raided CFMEU officers in Canberra and Brisbane.
“Neither of those raids results in any charges being laid against any union official.”
According to the ABC, a staff member arrived at the Pyrmont office this morning only to be escorted out by police.
