28 June 2010 | 10 minutes Canadian police have arrested over 600 people in Toronto in a police crackdown on protests at the G20 summit. Riot police used batons, plastic bullets and tear gas for the first time in the city's history. More than 19,000 security personnel were deployed in Toronto and a nearly four-mile-long security wall was erected around the G20 summit site at the Toronto Convention Center. The security price tag for the summit is estimated at around $1 billion. Franklin Lopez of the Vancouver Media Co-Op filed this report from the streets of Toronto.
