A major intersection in downtown Winnipeg is closed as police investigate a scene focused on clothing and blood in front of the MTS Centre.

Both the eastbound and westbound lanes of Portage Avenue are blocked by police tape. Westbound Portage is blocked at Smith Street and eastbound Portage is blocked at Hargrave Street.

Officers have been on the scene since before 4 a.m.

Police have not provided any details on the investigation other than to say they are “investigating a serious incident overnight,” and officers can be seen near a pile of clothing and a blood-stained curb.

They say the intersection will be closed throughout the morning rush hour.

Donald Street is also blocked at Ellice Avenue.
