A volunteer in Toronto Mayor Rob Ford's re-election campaign faces charges of assault, mischief and theft in connection with an alleged altercation at a Scarborough campaign office.

Toronto police say they were called to an office in the Warden Avenue and Lawrence Avenue East area in the city's east end at 3:30 p.m. ET on Wednesday.

Police allege that an altercation took place inside Ford's campaign office between a 60-year-old campaign worker and a 43-year-old man.

The younger man was "removed from the premises" and police allege the altercation continued outside the building.

According to police, the campaign worker kicked a camera out of the younger man's hand and "punched him in the face."

Police say people in the area helped break up the fight, at which point it is alleged that the 60-year-old left with the man's microphone.

On Thursday, police announced  that the campaign worker had been charged. William Byers is due to appear in a Toronto court on Oct. 7.

The mayor's brother, Coun. Doug Ford, told reporters that he supports the campaign worker.

"This is a 60-year-old man who came in to volunteer his time to make phone calls, to help out on a campaign," he said.

The election is on Oct. 27. Rob Ford is up against dozens of candidates vying for his job.
