TORONTO - News that Toronto police had caught two people allegedly responsible for G20 violence was followed up quickly Friday by authorities issuing arrest warrants for three more suspects.

Protests during the summit last month erupted into violence -- police cars were torched and downtown storefronts were destroyed -- for which police allege a small group of people were responsible.

Cody Caplette, 21, was arrested Thursday and is accused of damaging a police car during riots on June 26. He is charged with threatening a police officer, and mischief over $5,000.

Also arrested Thursday was Phillip Lee, 28, who is charged with assaulting a member of the public, mischief, and theft over and under $5,000. He is accused of damaging a police car and stealing a police radio.

Hours later Toronto police announced they had issued arrest warrants for three more "most wanted" suspects.

Kurt Roarco, 22 of no fixed address is wanted for arson for allegedly setting a police car ablaze, and mischief over $5,000.

Michael Corbett, 29, of Toronto is wanted for mischief over $5,000 for allegedly kicking out a window and lights of a police car.

Officers are also seeking Bryan O'Handley, 19 of Toronto, on a charge of mischief over $5,000 and a underage boy who cannot legally be identified.

Investigators released photos of 10 "most wanted" suspects Wednesday in hopes that the public could help identify them.

Det.-Sgt. Gary Giroux of the G20 investigative team said police are still looking for about 60 suspects in total, and plan on releasing photos on a weekly basis.

"I suspect next Wednesday we may put out as many as 20 (new names of suspects)," said Giroux.

On the first day of the summit, some masked protesters dressed in black broke off from a peaceful demonstration. They destroyed storefronts and set police cars on fire, then ran back into the crowd and shed their disguises.

The photos released this week include that of a masked man swinging a bag of rocks over his head while defiantly looking at the camera, and an image of another man pulling something out of a smashed-in car window.

Giroux said the man with the rocks caused thousands of dollars in damage to stores on Yonge Street, and assaulted a journalist.

Police said Caplette is the man wearing a blue shirt and baseball hat in one photo released Wednesday. Lee's photo was never released.

Giroux said tips from the public helped police make the arrests.

Several more photos and videos of suspects are available for viewing on Facebook, Youtube and Twitter.

As of Friday investigators had received more than 17,000 photos and videos from the public.

"It's a lot of material to go through," said Giroux. "There'll be repeating themes and you'll see them again and again in the crowd and you start to almost get in tune with their faces."

People are being urged to drop off photos and videos from the protests to police, or to upload them to a police website.

Earlier this week Ashran Ravindhraj, 25, turned himself in to investigators. He is charged with arson and two counts of mischief over $5,000. Police allege he smashed windows and burned a police car.
