About 40 Idle No More protesters briefly closed lanes on King Street downtown during the afternoon rush hour.

The protesters were demonstrating to show their support of other aboriginal communities that are opposing exploratory drilling for shale gas in New Brunswick.

There was heavy police presence and at least one arrest, although protest organizers said the man arrested was not part of their demonstration.

Aboriginal communities across Canada have been staging protests against the exploratory drilling in New Brunswick. The protests spread outside the province after confrontations with police there earlier this month.
