Police are investigating claims that children were sexually abused on board two Cunard cruise liners.
According to Wiltshire Police, the investigation is focusing on allegations of sexual abuse by a crew member on board the Queen Mary 2 and its sister vessel the Queen Elizabeth.
The police, who are working closely with the NSPCC, have confirmed that they would be contacting all the parents who they needed to speak to.
The Mail on Sunday reported that detectives started the investigation after a tip-off and that the unnamed man, who is under investigation, lived in Wiltshire.
A Wiltshire Police spokeswoman told the newspaper: "We can confirm we are investigating historical allegations of child abuse by an employee of Cunard cruise liners.
"Inquiries continue. The employee no longer works for the company."
And a force spokeswoman said today: "We are unable to confirm any details at this time due to an ongoing investigation.
"However, we would like to reassure parents and the public that the police will be contacting all of the parents they need to speak to in the course of the investigation.
"If you are still concerned and would like some professional advice then you can call the dedicated NSPCC number 0800 980 4502.
"The NSPCC have advisors available who are aware of this matter and can assist parents if they have concerns about their children."
Cunard is part of the Carnival Corporation group - owners of the Costa Concordia, which ran aground off the coast of Italy - and operates the Queen Mary 2, the Queen Victoria and Queen Elizabeth cruise liners offering luxurious ocean travel.
A Cunard spokesman said: "We are deeply shocked by these allegations as the safety and wellbeing of our customers is of paramount importance to us.
"A thorough police investigation is under way which we are supporting and co-operating with fully.
"Given that the police inquiry is ongoing, we cannot comment any further at this stage.
"What we can say is that we are working closely with the NSPCC to ensure that affected families and children are cared for and offered appropriate support."
