Family of missing Ben Needham ask Facebook users to help solve 24 year-old vanishing mystery
The family of Ben Needham are hoping a social media campaign on the 24th anniversary of his disappearance could lead to new information to help their search.
Ben, from Sheffield, was 21 months old when he vanished on July 24 1991 after travelling to the island of Kos with his mother and his grandparents.
Today, the family has taken to social media to try to encourage as many people as possible to share an appeal about missing Ben.
The official Facebook page "Help Find Ben Needham" said it would be posting pictures throughout the day - including a special photograph at the time Ben went missing - to help raise awareness.
The campaign is also urging people to sign up to a Thunderclap, which will post an appeal about Ben's case on supporters' Facebook and Twitter accounts at midnight.
More than 1,700 people had signed up to the event, which is expected to be seen by more than 1,250,000 people.
People were also being urged to change their profile pictures to one showing a photograph of Ben as a 21-month-old alongside an artist's impression of what he would look like now.
A post on the Help Find Ben Needham page said: "As today is the 24th anniversary of Ben's disappearance, we will be sharing various pictures throughout the day.
