POLICE are investigating allegations that a Liberal campaign volunteer threatened the sister of western Sydney Labor MP Ed Husic with a Stanley knife.

It is the second incident involving police and Liberal staff in the past two days.

The Daily Telegraph has learned that on Wednesday night, a group of Liberal Party campaign workers rushed Mr Husic's sister, Sabina Husic, with the knife yelling "you f..king dog".

The alleged incident occurred when Ms Husic and colleague were patrolling Labor posters in Mt Druitt, in the seat of Chifley, after reports they had been vandalised, when they were set upon by three cars.

A witness said four men, including Jeremy Greenwood, a campaign volunteer for Liberal candidate Isabelle White, approached Ms Husic yelling abuse. One of them was holding a Stanley knife.

A complaint was made to Mt Druitt police and the NSW Liberal Party campaign head office.

It is believed Mr Greenwood has since been removed from the campaign, after photographic evidence - obtained by The Daily Telegraph - was supplied to the Liberal HQ.

Ms Husic declined to comment claiming the matter was under police investigation.

The Liberal Party, however, claimed their volunteers were the victims of Ms Husic.

A statement from Mark Neeham, NSW State Director, to The Daily Telegraph said: "On Wednesday night, a volunteer and a party member left the Chiefly campaign office to remove Liberal campaign signs that had been defaced and to replace them with new signs.

They noticed that a car seemed to be following them, fearing for their safety, they turned around to return to the campaign office.

The same car continued to follow them back to the campaign office, where the campaign workers got out of the car but the occupants of the car that had followed them remained in the car.

There were some words exchanged however there was no threat made by either side.

The local campaign immediately contacted police to report the activity of the car that was following them, the police attended the campaign office and a report was made to police."

A Liberal Party spokesman said the volunter was carrying a Stanley knife because they were cutting down posters.

Police confirmed they had been contacted about a "verbal argument" in western Sydney but said they had determined no criminal offence had occurred.

Police Media claimed no formal complaint had been made despite Ms Husic having given statements to police asking for the matter to be lodged as a formal complaint.

It is the second incident in two days involving police and Liberal campaign workers.

Local Victorian Police this morning raided the home of a Liberal staffer at 1am after claims that Liberal operatives had vandalised and stolen Labor campaign material for MP Anthony Byrne, and threw eggs at his car.

The Daily Telegraph has obtained a copy of a statement given to police last night by staff members for the member for Holt, alleging an office car we pelted with a dozen eggs by a Liberal operative.

"In addition 2 signs, size 1.2 metres by 2.3 metres were torn away from the trailer attached to my car and stolen," the statement by one of Mr Byrne's staff Nick McLennan said.

"My car was vandalised and covered with 12 eggs while parked no less than 50 metres from our electorate office in Fountain Gate."

The Australian Federal Police have also been asked to investigate, after a Liberal staffer known to Mr Byrne's staff, was seen close by after the incident which took place at 10.15pm last night.

Mr Byrne's signs were plastered with slogans about Mr Abbott's budget cuts.

The Daily Telegraph has learned that police conducted a search of a Liberal staffer's house and car at 1am this morning.

The Australian Electoral Commission has also been notified of the incident.

My Byrne holds the seat in Melbourne's south-eastern suburbs by a margin of 14 per cent, after winning a by-election in November 1999.

The development comes as Prime Minister Kevin Rudd and Opposition Leader Tony Abbott blitz key marginal seats on the final day of the gruelling five-week election campaign.

A Galaxy Poll for The Daily Telegraph predicts Labor faces a repeat of the 1996 election landslide that swept Paul Keating from power.

But Mr Rudd continues to put on a brave face and this morning posed for numerous photographs with students at St Edward's College in Gosford.

Mr Abbott started the day in Melbourne where he visited the Maton Guitars factory with opposition treasurer Joe Hockey and Victoria Guide Dogs with his daughter Frances.
