Cheyenne police are mourning the loss of a retired K9 officer who served the department for six years.

"It is with great sadness that we announce the passing of retired K9 Niko this afternoon, six days shy of his fourteenth birthday," police posted on Facebook Wednesday.

During his career, Niko assisted the department's patrol division with deployments resulting in the safe apprehension of suspects, recovery of illegal narcotics, and evidence.
