South Yorkshire Police say there is no "direct correlation" between Ben Needham's disappearance and a girl found in Greece.
The girl is suspected to have been abducted after the couple claiming to be her parents turned out not to be related after a DNA test.
She was discovered in a Roma gypsy camp, where there had been a reported sighting of Ben who disappeared from a Greek island 21 years ago.
"South Yorkshire Police is aware of the case currently being investigated by Greek police after a young girl was found at a Roma settlement in the country.
"At this stage there appears to be no direct correlation between this and the disappearance of Ben Needham, who was 21 months old when he went missing on the island of Kos in 1991.
"The case of Ben Needham continues to be investigated by the Greek authorities and South Yorkshire Police continues to support his family.
"No investigation is currently being carried out by the force in light of this recent case and officers from South Yorkshire Police will only become involved should authorities in Greece require our assistance."
