Dozens of people have contacted South Yorkshire Police with information about the disappearance of Ben Needham from Sheffield.
Two detectives from the force appeared on Greek television alongside the Needham family on the hugely popular Light at the end of the Tunnel show, a show about missing people which is watched by around 50 per cent of the Greek audience.
During the three hour show, which focused almost entirely on the disappearance of Ben, calls were received by call handlers on the show.
At the same time, the Operation Ben team - a team of highly trained and specialist detectives who work solely on the case - were on hand at their base in Sheffield to take calls from the Greek public.
Detective Superintendent Matt Fenwick said the force received 85 calls and emails in addition to those received by the television show.
He said a team of dedicated officers will work with Greek authorities to follow all the lines of enquiry.
Ben was just 21 months old when he disappeared from the village of Iraklise, Kos, on 24 July 1991.
Despite hundreds of reported sightings over the years, he has not been found.
Earlier this year, South Yorkshire Police received £700,000 from the Home Office to fund a dedicated team of nine officers to focus on the investigation and assist Greek authorities in continuing the search for him.
Independent charity Crimestoppers has also offered a reward of up to £10,000 to anyone who provides information which leads to the discovery of Ben.
Det Supt Fenwick said: “It has been really good and really positive.
“It was about appealing to the Greek public and the Greek communities. UK police haven’t appealed on Greek television doing an appeal in this way before.”
He called for people to not think about their own views on Ben’s disappearance and come forward with any information they have.
He said: “We ask people not to think about their own views. We don’t know what happened to Ben.
“We have a dedicated and experienced team, but that team is only as good as the information it receives.”
He added: “We want to establish what has happened to Ben for Kerry and for the whole Needham family and potentially give closure and potentially reunite Kerry with Ben, and I ask people to please help.”
Anyone with information about the whereabouts of Ben can call the Operation Ben team on 0114 296 3022 or email email@example.com.
