An Occupy Toronto protester who says she suffered a fractured eye socket and severe bruising during a confrontation with police is vowing to fight the charges against her.

Angela Turvey, 36, was charged with obstructing a peace officer and assault with intent to resist arrest during a scuffle with police on Friday.

"This is the worst thing that has ever happened to me," Turvey told reporters outside Old City Hall after she was released on bail Saturday afternoon.

She pulled her hair back to reveal several stitches above her right eye and said she was still in pain from Friday's altercation. Both of her eyes appeared bruised and swollen.

Turvey's lawyer, Michael Leitold, said he believes the Special Investigations Unit should be called to investigate his client's confrontation with police.

Turvey's appearance in court earlier Saturday was met with audible gasps from the audience, which included about two dozen members of the Occupy movement.

Turvey and three others were arrested Friday after police asked the Occupy group to remove tents they had set up outside a downtown courthouse at 361 University Ave., near Osgoode Hall.

Police maintain that was the second time they had asked the protesters to remove their tents and had to forcibly remove the group after they didn't comply.

Occupy Toronto alleges the protesters -- two men and two women -- were "brutally beaten" during the arrests.

Video uploaded to YouTube appears to show a police officer trying to restrain Turvey as she cries out, face down on the pavement. At one point, she turns her face towards the camera and it looks as if part of her face is swollen.

Speaking to reporters, Turvey's father Leslie said he has several questions about his daughter's arrest.

"It seemed to have been a pretty peaceful situation, why the police were there is beyond me," he said. "As well, why did they have to target my daughter?"

Leslie said his daughter has a serious pre-existing neck problem but police ignored her attempts to share this information with them.

"Doctors have told her that she's not to put her arms behind her back because it could paralyze her," he said.

Turvey said she travelled to Toronto about two months ago to join the Occupy movement. She said Friday's incident was the first time she clashed with police.

"Usually I have a good relationship with the officers," she said.

John Erb, another arrested protester due in court, had his case moved to the federal level because it relates to drug possession. The 44-year-old faces a string of charges including assault with intent to resist arrest and possession of marijuana.

Craig Poirier, 35, and Alice Evonic, 19, were also arrested during Friday's incident.

An Occupy Toronto rally took place in front of Old City Hall Saturday afternoon. The protesters were demanding that police drop the charges against the four who were arrested. They later moved to Toronto Police 52 Division.

Two other Occupy Toronto members were reportedly injured by police on Friday during a march through the downtown core protesting the University Avenue arrests.

A separate downtown protest against the federal election robocall scandal also slowed down traffic in the area.
