TORONTO - A bail hearing for a group of people that police say include alleged ringleaders of the G20 protests will continue into Wednesday.

At least 15 people have been identified as part of a police investigation into activities of people planning violent G20 action, defence lawyers have said.

Four alleged anarchists accused of having organizing roles are among those seeking bail, but any evidence entered at their hearings is under a publication ban.

Leah Henderson, Amanda Hiscocks, Peter Hopperton and Alex Hundert are alleged to be members of the Southern Ontario Anarchist Resistance.

They were arrested before police cars were set aflame and storefronts vandalized during a G20 protest on June 26.

The mass bail hearing listed 19 names on the court docket, including those four.
