A criminal investigation has been launched in Australia into how cruise ship passengers were allowed to disembark in Sydney despite some exhibiting flu-like symptoms.
More than 600 people on board the Ruby Princess later tested positive for coronavirus and 10 have since died.
The ship remains off the coast with nearly 200 sick crew members on board.
Police in New South Wales said they would look into whether national biosecurity laws had been broken.
Australia has so far reported 5,548 coronavirus cases and 30 deaths.
Those sickened on cruise ships account for nearly a tenth of all cases in Australia.

The New South Wales government has faced mounting criticism for allowing people off the ship but has insisted that the decision was based on expert advice.

The Ruby Princess with about 2,700 people on board arrived in Sydney last month after an 11-day cruise.
According to NSW Health, about a dozen passengers had reported feeling unwell and had swabs taken for Covid-19. One was taken by ambulance to hospital.
But other passengers on board weren't told of this. Instead, they streamed off the boRead More – Source
