Heartbreaking moment police officer comforts his dying horse as she took last breaths

This is the heartbreaking moment a police officer comforted his dying horse on the street as she took her last breath.

Charlotte, a six-year-old patrol house, became "spooked" and ran into the path of an incoming cement truck.

Officer D Herrejon refused to leave her side as she lay fatally wounded on the roadside in Houston, Texas.

The driver of the truck is not believed to be at fault in the tragic incident.

Officer Herrejon was taken to hospital to be treated for minor injuries.

In a touching tribute, Houston Police Department shared pictures of Charlotte during her four years "serving the citizens of Houston".
