Warrnambool detectives have completed an investigation into a threatening letter sent to the Port Fairy office of an Upper House MP.
A Victoria Police spokeswoman said the investigated into a document which was delivered to an office in Port Fairy during January had concluded and no charges would be laid.
The copy of an email threatening state Western Victorian Upper House member Bev McArthur was alleged to have come from the office of neighbouring South West Coast MP Roma Britnell.
Even though they are both Liberal Party members, Ms Britnell and Mrs McArthur are seen as political rivals.
Ms Britnell denied any involvement and initiated a complaint which led to a police investigation.
The copy of the email, which was contained in a letter, was provided to Warrnambool police and the Victorian Parliamentary Security Committee.
The letter was addressed to Mrs McArthur's employee Jennifer Lowe at the Upper House MPs' Port Fairy electoral office.
The email print out purported to be from Ms Britnell to one of her employees, Jarrod Woolley.
The email says Mrs McArthur and Mrs Lowe were problems and needed to be "taken out".
The email was allegedly sent in January, printed out in July and brought to the attention of police about July 12.
In late August Detective Senior Constable Wayne Ryan, of the Warrnambool police crime investigation unit, said the investigation was still ongoing.
That investigation, including forensic tests and the examination of computers and email accounts in Ms Britnell's office, has now been completed.
Today Ms Britnell said Victoria Police has advised her that it had concluded its investigation into the hoax email.
"Police have advised me that there is no evidence that the email came from me, my office or devices associated with me or my office," she said.
"I thank the police for their assistance in this investigation and their assurances that if new information comes to light the case would be reopened," she said.
The Victorian Parliamentary Security Committee also decided to take no action.
