( CNN ) -- A zookeeper was in stable condition at a Sydney hospital Saturday , a day after she was crushed by a young male elephant during a training session . Lucy Melo , 40 , is recovering in Royal North Shore Hospital -- her condition apparently steady , the Taronga Zoo said in a statement . `` We 're all relieved to hear Lucy 's condition remains stable , and we 're continuing to provide support for her family and fellow keepers , while we continue our programs for the whole herd , '' said zoo director Cameron Kerr . The 2-year-old elephant -- known as Pathi Harn , which means miracle in Thai -- pinned Melo to a post around 11:30 a.m. , according to the zoo . Two other zookeepers at a nearby stall came over , got the animal off Melo and called for an ambulance . The Sydney zoo launched an investigation , but as of Saturday it was unclear why Pathi Harn `` challenged '' the zookeeper . That young elephant and the rest of the herd are `` calm and well and in the elephant paddock as usual , '' according to Taronga . These pachyderms , in fact , are going about life as usual -- including normal daily activities . An Asian elephant , Pathi Harn showed no signs of his life while his mother was in labor for eight days before his birth -- alive and well -- at 3:27 a.m. on March 10 , 2010 , according to Taronga 's website . Weighing in at 116 kilograms ( 255 pounds ) at birth , he grew to 506 kilograms by his first birthday . The zoo 's website describes him as a `` very happy calf who is always looking for attention . '' `` Playful and inquisitive , '' Pathi Harn is often found `` sparring and wrestling '' with Luk Chai , a 3-year-old elephant at the zoo .
