Hamilton police are investigating whether remains found in the east end Tuesday afternoon are human are animal.

Police were called to Arvin Avenue near Barton Street around 12:30 p.m. for “suspicious circumstances,” Const. Debbie McGreal-Dinning told CBC Hamilton.

“There are remains, but we’re not yet sure if they’re animal or human,” she said. The coroner has been called in to help analyze the bones.

An officer is still holding the scene. Police should know by mid morning if the bones are human, McGreal-Dinning says.
