ADDING SALTIE TO THE WOUND AUTHORITIES have launched a second investigation into the Australia Zoo Wildlife Hospital over allegations of animal mistreatment.
It comes as a manager at the centre of the animal welfare scandal was yesterday seen being marched off the premises for alleged staff harassment. 
The Courier-Mail can reveal that the same curator has also been implicated in the shocking deaths of a saltwater crocodile and endangered species of iguana at the zoo.
Biosecurity Queensland has launched an investi-gation into animal welfare concerns at the hospital and will examine case files.
It is the second investigation by a government agency after the Veterinary Surgeons Board also -responded to an official complaint. The RSPCA has also received two more formal complaints about the zoo, which it has forwarded to Biosecurity Queensland.
Several sources say the turmoil and staff turnover engulfing the wildlife hospital actually started at the zoo where the manager was initially employed. He is -accused of enforcing decisions that led to the death of a 4m male saltie named Shaka that died after it was transferred from its warm pond in winter into an -enclosure with a cold pool.
Despite staff warning that the cold-blooded animal would not be able to -digest its recent meal in cold water, they were told to continue with the "croc jump", which was being filmed for American TV.
Sources say an endangered crested iguana named Turaga also died after the same manager bagged the animal incorrectly for transport to Melbourne Zoo. The stud lizard allegedly became tangled in the calico bag, which had not been turned inside out.
A spokeswoman for Australia Zoo would not comment on the harassment claims but confirmed a "workplace investigation" was under way.She said the cause of the croc Shaka's death was "unknown" and that the iguana had been bagged correctly but died due to "complications during transport".
