Provincial police say they have cleared the scene of an investigation in Tecumseh, Ont.
Few details have been released, but OPP appeared to be searching a large area on the west side of the town Sunday.
Police asked the public to avoid the area between Riverside Drive and Tecumseh Road and Manning Road and Banwell Road for "an ongoing investigation" at 11:20 a.m.
The scene has been cleared and there is no threat to public safety as of 2 p.m., according to a tweet from OPP.
