What appears to be a cow heart was found near a garbage can at Ryerson on Wednesday morning.

Later on Wednesday afternoon, Ryerson tweeted that the object was an animal organ, “apparently used in a student art project and disposed on Victoria Street.” That report is unconfirmed and Toronto police said investigation is underway to determine what the object is.

Police did say it was too big to belong to a human.
