From The Associated Press:

TORONTO — Police conducted a large raid and rounded up more protesters Sunday in an effort to quell further violence at the global economic summit after black-clad youths rampaged through the city, smashing windows and torching police cruisers.
Police said they have arrested more than 500 demonstrators, many of whom were hauled away in plastic handcuffs and taken to a temporary holding center constructed for the summit.
