After several weeks of standing idle, London Police say members of the 'Idle No More' movement plan on returning to the downtown core.

Police say they've received "communication" from Idle No More organizers that a "large group of supporters will be demonstrating" at Dundas and Richmond starting at 12 p.m. Thursday. March 21st has been designated as a Global Day of Action.

AM980 will have a reporter on hand.

All LTC buses in the downtown core will be on a detour from around 11:45am until 1pm.

London Police say they expect a peaceful protest, similar to past demonstrations, although motorists are being told to prepare an alternate route while the protest is underway.

Previous demonstrations have lasted for less than an hour.
