A two-metre South American boa constrictor is on the loose after police mistakenly believed it was a harmless python and set it free. A bizarre search is now unfolding on Queensland's Gold Coast as authorities try to locate the reptile which could pose a threat to local wildlife and even people's pet cats and dogs. Snake catcher Tony Harrison warned that if the large-predatory boa has Inclusion Body Disease 'it can be unbelievably contagious if that gets loose in Australia'. Mr Harrison told Daily Mail Australia: 'Police should have called the snake catchers and we'd have euthanised it. That was very silly of them.' Scroll down for video . Queensland Police found the snake at the base of a tree on a footpath (pictured) in Surfers Paradise and then released it into the wild . Queensland Police say officers were called to The Esplanade at Surfers Paradise on or about March 26, to respond to reports of a large snake spotted at the base of a tree on a footpath. The officers released the reptile into bushland at the Southport Spit, but the incident has since sparked an operation by Biosecurity Queensland officers who say the snake isn't a harmless python after all. Mr Harrison believes the snake - likely to be an illegal import that was kept as a pet - will be found 'within a month' but there are fears if the boa is pregnant there could then be up to 30 live young on the loose. The reptile which could pose a threat to local wildlife and even people's pet cats and dogs (stock photo) South American boa constrictors  have varying patterns of cream, brown, tan, gray, and black with ovals and diamonds . 'They can eat up to three times their girth, no more or less than pythons and including a cat or small dog, but the biggest problem is if it was going to give birth,' Mr Harrison warned. Biosecurity Queensland is working with the Gold Coast City Council in a bid to find the snake. 'Police originally caught it in a sheet after spotting it under a tree in Surfers Paradise before they released it in bushland at The Spit,' a spokesman said. 'They say they captured the snake when it started moving towards people.' South American boa constrictors are pinkish or tan in color and have varying patterns of cream, brown, tan, gray, and black with ovals and diamonds.
