Toronto police say they are getting a "remarkable" response from the public in their quest to identify suspects from violent G20 protests.
Police have been providing photos of suspects and Detective-Sergeant Gary Giroux says more than half were identified within 12 hours of their release.
Another 21 photos were displayed Wednesday, although Det.-Sgt. Giroux told a news conference some may have been released before.
He added an arrest warrant has been issued for Kelly Pflug-Back on charges of mischief over $5,000.
Det.-Sgt. Giroux alleged she was an organizer who was responsible for thousands of dollars in damage.
He said 10 people have been arrested and charged with a total of 21 offences related to violent protests during last month's G20 summit.
The posting of images follows the release of a 10 "most wanted list" on July 14 and the issuing of suspect photographs a week earlier.
Police are combing through thousands of images and videos received from the public to root out those responsible for G20 violence and vandalism.
As of last week, the G20 investigative team said they had received more than 14,000 still images and more than 500 videos.
On Tuesday, one man facing explosives and weapons charges as part of a G20 investigation was denied bail.
Byron Sonne was arrested on June 22, just days before world leaders descended on Toronto for the summit.
The 37-year-old Internet security expert faces charges of possession of explosives, dangerous weapons, intimidation of a justice system participant and mischief.
The evidence presented in court and the reasons behind the decision are under a publication ban.
