TORONTO - For the second Saturday in a row, protesters are expected to gather at Queen's Park to demand an independent public inquiry into police actions during last month's G20 summit.

The march will be preceded by a "bubble-in."

Several hundred people are set to gather with plastic wands and bottles of soapy water after a video dubbed "Officer Bubbles" spread on the Internet.

The video shows a stern police officer threatening to arrest a young woman during a protest if the bubbles she is blowing touch him.

More than 1,000 people were arrested over several days last month when world leaders descended on the city.

On Wednesday, police released a 10 "most-wanted" list of G20 protesters still at large. Since then, they've made two new arrests and have issued warrants for three more people from the list.
