Mississauga mayoral candidate Alvin Tedjo says a volunteer with his campaign was attacked by a person with a knife while putting up election signs in a residential neighbourhood on Monday night.Tedjo says thankfully the victim wasn’t seriously injured and a suspect was arrested.“Last night, one of our volunteers was confronted by a stranger and attacked with a knife while installing election signs,” Tedjo wrote in a statement on Tuesday. “I have spoken with the victim to offer my support as they recover from this altercation. I have also been in touch with Peel police as they investigate this incident.”CityNews spoke to Tedjo about this incident on Tuesday as he was casting his vote at an advanced polling station. He said the volunteer was with his adult son when he was approached by a stranger who took offence at him putting the sign on the lawn of a home.“They said ‘We don’t want that here, I don’t want that here’ … and (the volunteer) said ‘the homeowner gave us permission to do this,’ and then it escalated from there.”The alleged attack took place in the Truscott Drive and Southdown Road area at around 7:30 p.m., Tedjo said. When asked about the victim’s injuries, Tedjo said he wasn’t aware of the full details, but that “a knife was brandished and put in his face and he was hurt by it and police are investigating.”CityNews has reached to Peel Regional Police, but so far they have not released any details about the incident.

Last week, Mississauga mayoral candidate Bonnie Crombie filed a police report after she says she was threatened by someone who said if attended yesterday’s debate she would face “serious consequences.”Crombie did attend the debate, and Peel Regional Police have confirmed they are investigating the threat. While casting her advanced vote on Tuesday, Crombie touched on the incident.“We certainly have seen an uptick in some very negative behaviour. I’ve just gotten off the phone with Alvin Tedjo when I heard about the volunteer attacked with a knife. That is completely unacceptable. I hope the person is alright,” Crombie said.Crombie admitted that the tone surrounding the Mississauga race has been rather unpleasant, with the bad blood spilling over in the first mayoral debate last Thursday involving the four top candidates. “The tone, the lack of civility, the lack of decorum has really been increasing, the behaviour last Thursday night was frankly rather Trumpian.”
