A Norwich pensioner who died after suffering a heart attack on board a cruise ship which is believed to have been hit by the vomiting bug norovirus has been named.

Hundreds of passengers and crew on the Marco Polo, which is berthed in Invergordon, Easter Ross, have shown symptoms of the norovirus.

Five people have been treated in hospital after falling ill on the ship while a sixth was airlifted to hospital after developing a medical condition unrelated to the suspected norovirus outbreak.

Roy Sillett, 74, a retired man, from the city, is believed to have suffered a fatal heart attack on board the ship yesterday and his death was unrelated to the bug.

NHS Highland said Mr Sillett had serious underlying health problems and a post-mortem examination would be carried out to establish the exact cause of his death.

According to NHS Highland, about 380 people on board the ship had become ill with suspected norovirus.

Those taken unwell on the ship have been treated by a team of GPs and local nurses.

Of the 380 people with symptoms, 340 were passengers and 40 were crew members,

Those not showing symptoms were allowed to go ashore on Monday after port health officials inspected the ship.

The ship has not been detained or placed under quarantine but has remained in Invergordon to allow extra manpower to join the ship, according to Transocean Tours.
