SAILORS onboard a Royal Navy ship were rushed to hospital today after reportedly drinking contaminated water.
HMS Portland diverted to Portsmouth Naval Base on Friday when a sailor noticed water had been "contaminated".
Scientists boarded the Frigate after crew were taken to hospital with suspected poising.
A source told The Sun it was a mistake onboard.
A Navy source told The Sun: "The person who committed this mistake acted with honesty and integrity to let senior officers know what had happened.
"If they were not to do that this could have been a whole lot worse.
"Integrity and honesty are key components of the Royal Navy and we are glad they have been upheld."
It is unclear what got into the drinking water at this stage.
The Ministry of Defence confirmed water onboard had been contaminated.
