Ben Needham disappeared on 24th July 1991 when he was just 21 months old.
Ever since that fateful day her little boy vanished, Kerry Needham has campaigned tirelessly for police to continue investigating Ben’s disappearance.
And now, in a bid to boost the search for the missing boy, Crimestoppers have offered a £10,000 international reward to the person who finds evidence that helps bring Ben home, twenty-five years after he disappeared.
Detective Inspector Jon Cousins said: “We’ve worked with the Greek authorities and we are delighted they have allowed this incentive to be offered and paid in euros.
"We have specific lines of inquiry we are pursuing but it could also help provide the breakthrough we need.
“I am convinced someone somewhere must know what happened to Ben, and this is what we are here for.
“We hope this added incentive will be the catalyst for someone coming forward with the breakthrough piece of information and evidence we need to find out what happened to him.”
Kerry Needham, the mother of the missing child, added: “I finally feel we are getting help. It has taken a long time to get to this stage but it feels like we are finally breaking through. It’s amazing to know the British police are in Kos right now.”
In 2015, South Yorkshire Police secured £700,000 of Home Office funding to fund an investigation into his disappearance.
And, in May of the same year, an appeal made on Greek TV led to more than 200 calls and emails being received by the force - and police have now confirmed that they are investigating several ‘very interesting’ new leads.
As a result, British detectives are now preparing to spend up to two weeks on the Greek island of Kos, where they will speak to at least seven people in regards to Ben’s disappearance.
Detective Inspector Jon Cousins said previously: "[The Greek authorities] have given us every assistance that we require and that's allowed us to really progress this a lot further than where I thought we would be at this time.
"We're going to continue with our efforts looking in to everything that we have so far and, as we're going along, we're turning up new leads all the time that are very interesting to use.
"We're going to make sure that we pursue each and every one of those to try and find an answer for ourselves as well as for [Ben's mother] Kerry and the family."
Last year, Kerry penned a special open letter, which she hoped would be read by her son.
The letter, which was also translated into Greek on the Help Find Ben Needham website, reads: "This is a direct appeal to anyone who is around 25-years-old and possibly living with a family who you look nothing like, I beg you to get in contact with me.
"I promise to cause no problems for your family who you live with, I just want you to know the truth about what happened to you and to know you are healthy and happy.
"A simple DNA sample can be taken from you without causing any distress to anyone.
"So if you think you were born in 1989 and you have blue/grey eyes and a possible birthmark on your leg, YOU could be Ben!!!"
She continued: "Twenty-three years have gone by Ben and I love you just as much today as I did the day you were born.
"Please anyone get in touch and end all this pain your family feel living without you."
