Northumberland OPP are appealing for information on the origins of a cross bearing apparent satanic symbols found on a Lake Ontario beach earlier this week. On Wednesday, identification officers were called to the beach at the Nawautin Nature Sanctuary in Grafton, about 14 kilometres east of Cobourg, after numerous social media posts Tuesday featured photos of an upside down cross with etchings on it at the beach. Some of the symbols included a pentagram.
