During a routine training session at about 11.30 am this morning in Taronga Zoo’s elephant barn, an incident occurred whereby a young male elephant pinned a female keeper against a bollard.Two other keepers in an adjoining stall responded to her call and moved the elephant away.An ambulance was immediately called and took her to Royal North Shore Hospital where she is receiving treatment.The Zoo is waiting for confirmation about her condition from the hospital.Senior Taronga Staff have accompanied the keeper to the hospital to provide ongoing support.An investigation has been immediately commenced into this incident and what may have prompted the reaction.It’s unknown at this time why the young elephant challenged the keeper.The public were not at risk at any time and the elephants are now in their paddock at the Zoo.The Zoo will hold a media conference this afternoon when more details are available.
