There have been more acts of intimidation directed at the campaign of Toronto Liberal candidate Carolyn Bennett.

Police are already investigating a number of acts of vandalism — including cutting the brake lines on cars — against Bennett supporters in Toronto's St. Paul's riding over the weekend.

On Monday the harassment continued.

"A family with a sign … received a threatening phone call saying, 'Take your sign down or you'll be next,'" Bennett told CBC News on Tuesday.

"Two other people later last evening [Monday] called with a similar story.

"They were very, very frightened," said Bennett who said she believes the most recent actions are "an intimidation tactic as opposed to this life-threatening approach to the brake line which has just sickened us all."

Toronto police launched a criminal investigation on the weekend after more than 30 cases of vandalism were reported in St. Paul's and in Parkdale-High Park. At least 17 of the cases involve cutting of automobile brake lines.

Some homes and garages were sprayed with anti-Liberal graffiti in the riding.

Police said the only connection between all of the cases was that all of the victims had signs supporting Bennett on their lawns.

Bennett said Tuesday that although some people in her riding have asked for the signs to be taken down, others have asked her campaign to put up signs, as a way of showing they won't be intimidated.

"One person even phoned and said, 'I'm not voting for you, but I want your sign,'" she said.

Liberal supporters were also victimized in similar incidents during byelections in Guelph in August and in north Toronto, in the Willowdale riding, in March.
