Flynn's Beach in Port Macquarie

A human bone has been discovered near a Port Macquarie beach almost a month after another bone was found in the water at the same beach.

A small bone, believed to be human, was found by passers-by yesterday afternoon in the vicinity of Flynn’s Beach, NSW Police said in a statement.

It has been seized by police and will be forensically examined. Any results will be compared with missing person records.

On June 15, a spear fisherman contacted police after finding a bone in the water at Flynn’s Beach. No other items were found during a search a day later.

More bones were found by another spear-fisherman at nearby Flat Rock, east of Nobby Head, on June 17.
