Local animal-control officers are investigating the discovery of some wild animal dens -- possibly belonging to coyotes -- in the Lake Mohegan open space.

The Conservation Department notified animal-control staff about the discovery last week.

When an animal-control officer checked the next day, he discovered four dens in the town-owned property, either being used by coyotes or foxes. They planned to set up a camera to determine what wildlife is inhabiting the dens. If the animals are coyotes, animal-control officers usually attempt to relocate them.

Police said a sign would be posted to alert hikers about the possibility of the animal lairs.
