(CNN) -- A 10-year-old zebra at the National Zoo in Washington bit a staff member several times Monday morning, according to zoo officials.
The injured zookeeper was alert and talking after the incident, but was taken to a hospital as zoo officials continued to investigate what happened.
They said the incident apparently led to the death of a young gazelle, which probably was spooked by the biting zebra. A necropsy report shows fractured vertebrae that could have been sustained when the year-old gazelle, named Tony, ran into a barrier.
The biting zebra, known as Gumu, was unharmed and has been taken out of the zoo's zebra exhibit.
