( CNN ) -- The charity taking care of a blonde , blue-eyed girl taken by police from a Roma community in Greece has received 8,000 calls from around the world since it issued a call for help in finding her parents . `` At least eight calls have some information that can be used by the police for further investigation , '' Smile of the Child spokesman Panagiotis Pardalis said Sunday . `` Four of these calls are from the United States . '' The group is working with Greek authorities , Interpol and Europol to solve the mystery of Maria , the name by which the couple posing as her parents called the 4-year-old . `` This Roma family had 14 children in total , and they were registered with fake birth certificates , so now the police are trying to see whether these children also belong to this family or if there is something else behind this , '' Pardalis said . The girl was immediately taken from the couple and entrusted to the care of the Smile of the Child , which will keep her in one of its group homes until her family is found . `` The girl is at peace , '' Pardalis said . `` She is doing much better . '' A prosecutor became suspicious when he saw the child with very pale skin in a community of Roma , also known as gypsies , near the town of Larissa in central Greece , Pardalis said . `` It was bad living conditions , poor hygiene . The girl was found in a state of neglect , both physically and psychologically , '' he said . `` We do n't have any other information , if this girl was forced to work or to beg on streets . '' When the couple was questioned , `` they changed repeatedly their story about how they got the child , '' a police statement said , compounding the officers ' suspicions . DNA testing then `` showed that there was not any genetic compatibility '' between the girl and the 39-year-old man and the 40-year-old woman , the police said , meaning they can not be her biological parents .

The two people posing as her parents have been arrested and face charges of abducting a minor , as well as counts of falsifying identity documents , said the state-owned Athens-Macedonian News Agency . Among the suspect documents found by police was a 2009 birth and baptism registration from Athens authorities , the news agency said . The woman also had two different valid identification documents and , based on family registration records , appears to have given birth to three children between June and November 1993 and another three children between October 1994 and February 1995 , it said . In fact , the state-run AMNA news agency reported , she had two family residence registrations indicating that she was mother to 10 children : five girls and a boy in Larissa , plus four girls in Trikala . The man is registered as the father of four more children . Greece 's government has promised to help the child . In the meantime , the little girl is being given support by a police psychologist , the police said . Anyone with information is asked to call the European Hotline for Missing Children or contact the Smile of the Child . The girl 's discovery will probably prompt speculation that she may have been abducted or trafficked , which , if proved , could serve to fuel prejudice against the Roma community within Greece and elsewhere . Rights group Amnesty International has called on the European Union to take action to end discrimination against the 6 million Roma , describing them as `` the largest and most disadvantaged minority in the region . '' In May , Amnesty International said Greece had been found guilty of discrimination against Roma schoolchildren in three rulings by the European Court of Human Rights . CNN 's Laura Smith-Spark and Joseph Netto and journalist Elinda Labropoulou contributed to this report .
