The Vancouver Police Department says it has tracked down three people in the U.S. suspected of taking part in the June 2011 Stanley Cup riot.

The suspects are in Washington, Alaska and one is believed to be in Illinois.

Vancouver Police Constable Brian Montague says a Canada-wide warrant for participation in a riot and other charges has been issued for their arrests.

Montague says the suspects have been told of the warrant by their local police and know they will be arrested if they try to enter Canada.

Two of the suspects are Americans, but one is a Canadian citizen from Vancouver believed to be studying in the U.S.

He says an application to U.S. authorities to extradite the three has been discussed, but not officially filed.
