The woman accused of being a key organizer in protests during Toronto's G20 summit pleaded guilty to eight charges Friday.

Kelly Pflug-Back, of Guelph, Ont., pleaded guilty to seven counts of mischief exceeding $5,000 and one count of wearing a disguise with intent.

Pflug-Back admitted to attacking two police cars and smashing windows at a number of stores over the violent weekend in June 2010.

However, there is discrepancy over her level of involvement. The crown believes her level of leadership in the attacks was greater than she admits and it intends to present evidence in court at her sentencing in May.

Pflug-Back, who was on Toronto police's "most wanted" list of suspects for G20 violence, surrendered to police in Peterborough, Ont., in July 2010.

She was later granted bail.
