Gatineau police are working to remove a human body part found in a chemical basin at a local pulp and paper plant.

Officers were called to Resolute Forest Products at 79 Main Street just before 10:30 a.m. ET Friday after employees made the discovery, said Gatineau police spokesperson Jean-Paul Lemay.

"It's a challenge because there are chemical products in the basin. It's an unusual operation for us," Lemay said.

"It's difficult to understand what could have happened. We'll start with the first step, which is to recover the body part, and then search the rest of the basin for more body parts."

The plant produces newsprint, specialty papers, tissue, and "market pulp and wood products," according to the company's website.

Officers were still on the scene as of  3 p.m. 

The particular body part has not been identified.
