A group of angry diners have said they intend to sue celebrity chef Heston Blumenthal for compensation after contracting food poisoning at his restaurant.

The Health Protection Agency carried out an investigation and found that shellfish contaminated with human sewage were to blame for the outbreak of norovirus poisoning and that sick staff continued to work with the food afterwards.

Boxing promoter Frank Warren was among those who fell ill and told the Daily Mail: "I am taking them to court and a lot of other people are too."

Earlier this month, the Ilkley Gazette reported that a number of diners are fighting for compensation after getting food poisoning from a restaurant called the Saffron.

According to the NHS, noroviruses are among the most common causes of gastroenteritis in the UK. They affect between 600,000 and one million people in Britain every year and can be spread by eating contaminated food.
