A 67-year-old man has been arrested after a package containing a mystery powder was tossed into WA Premier Mark McGowan’s electorate office in Rockingham.
The incident happened just days before West Australians are set to go to the polls in the state election on Saturday.
According to The West Australian, he was arrested just after 10pm on Tuesday at a Rockingham home.
As of Wednesday morning, no charges had been laid against the man who is said to be assisting police with inquiries.
He allegedly dropped a letter and an aluminium foil package to McGowan’s office.
“A package was thrown under the window at the front of the office at the staff … a guy ran in and ran out and did it,” McGowan told ABC radio.
“Because of who I am and the heightened situation with the election on Saturday, they evacuated the office.
“The police have come so I’ll head down there and make sure my staff are OK and see what’s going on.”
Police and firefighters were called to the office on Tuesday afternoon to investigate the item.
One staffer was taken to hospital and others had to be evacuated.
Tests are still being carried out to see if the substance in the package could be harmful to the health of McGowan’s staff.
A similar package was also delivered to the front desk of a nearby Federal Labor MP Madeleine King.
The West reported that it came with a letter that made accusations about the government trying to poison the writer.
The news comes after the premier also indirectly received a death threat on the campaign trail this week.
A spokesperson for McGowan confirmed it was made to Labor’s candidate for Carine, Paul Lilburne, at an early voting centre in Hillarys, in Perth’s north, on Monday.
WA Police are said to be investigating the threat.
