TORONTO - A 21-year-old woman police allege is responsible for thousands of dollars of damage during G20 protests will spend at least another week behind bars.

Kelly Rose Pflug-Back, of Norwood, Ont., surrendered to police in Peterborough on Wednesday.

The surrender came just hours after Toronto police issued a warrant for her arrest.

Investigators allege she was an organizer of G20 violence that saw at least five police vehicles burned and storefront windows smashed on June 26.

Pflug-Back, who is charged with six counts of mischief over $5,000, appeared briefly in a Toronto court today before being remanded into custody.

Her next appearance is set for July 27.
