There’s been a dramatic development into the alleged misuse of Health Services Union funds.

This morning police swooped on the Union’s Sydney head office and seized documents and computer equipment.

TRANSCRIPT

The raid happened at 9am, then just two hours later the suspended HSU National President Michael Williamson, was cornered by police in a nearby car park.

Police say they found a bag of documents “significant to their investigation” but they wouldn’t confirm any further details.

They say separate criminal charges of obstructing a criminal investigation or perverting the course of justice are possible.

Det Supt Col Dyson, NSW Police: “We won’t predict the most appropriate offence at this stage, only that we do have one further matter, perhaps two further investigations.”

Meanwhile, Australian Federal Police have launched a formal investigation into Peter Slipper.

The federal speaker’s been stood aside over allegations he misused Cabcharge vouchers.

Treasurer Wayne Swan has called for the Liberal Party to come clean over any role they’ve had in the affair.

His Trade Minister Craig Emerson accused Tony Abbott and Christopher Pyne of having prior knowledge of the allegations.

Wayne Swan, Federal Treasurer: “I’d like to see what has been the Liberal Party involvement in all of these allegations, ’cause they’ve got form, and we saw it in the Godwin Grech affair.”

But the Liberals have denied any wrong doing.

Josh Frydenberg, Liberal MP: “The government has no evidence for its claims against Christopher Pyne. He was doing his job, this is fanciful.”
