"We are getting a forensic pathologist in. It's nothing suspicious at this stage. It is up to the forensic pathologist to give us some guidance on that."
A police spokeswoman also confirmed that a fisherman had found an item "which he believed may be human remains".
"Police were called and we are currently examining the item and making inquiries. We don't have any other information we can provide at this stage," the spokeswoman said.
The fisherman declined to comment out of respect for the remains.
