COEUR D'ALENE, Idaho (AP) — A $10,000 reward is being offered for information leading to the arrest and conviction of whoever illegally killed wolf pups after removing them from a northern Idaho den.

The Center for Biological Diversity announced the reward Monday following the killing of the pups that Idaho officials say happened in the middle of May.

The Idaho Department of Fish and Game is asking anyone with information to call the Citizens Against Poaching Hotline. Callers can remain anonymous.

The Center for Biological Diversity says the killing of the wolf pups is an example of why a federal monitoring program of Idaho wolf management should continue.

The Center in March filed a notice of intent to sue the U.S. Fish and Wildlife Service involving the monitoring program that ended in May.
