The Woodland Park Zoo says it euthanized a monkey after it suffered a broken leg in a move.

The zoo says the patas monkey named Kyle also suffered a brain injury when it was caught in a net Feb. 28 for a move to temporary cage. The zoo needed to move the monkey to improve its sleeping quarters at the African Savanna exhibit.

The zoo says the move was carefully planned to minimize stress.

KOMO reports ( http://bit.ly/YmhA10) the organization In Defense of Animals says the zoo failed to follow proper procedures. It has filed a complaint with the U.S. Department of Agriculture.
