Wild bears have been making frequent visits to a cemetery in the historic city of Kostroma in central Russia where amputated human body parts were recently scattered, local police reported on Thursday.

Investigators believe that the human remains were dumped at the cemetery illegally by one of the local hospitals in the beginning of October, and the stench of decomposing matter attracted bears to the site.

“Police have received several complaints about wild bears walking around the cemetery from the local population,” a police spokesperson said. “We suspect that the appearance of wild animals in the area was caused by this illegal biological waste dump site.”

A team of hunters has been dispatched to the cemetery to track and kill the scavenging bears.

The cemetery has been temporarily closed to visitors.
