Greece Charity In Appeal Over Mystery Girl An international search is under way to identify the parents of a blonde girl found in the care of a couple on a Roma camp in Greece. DNA tests have shown the four-year-old is not related to the couple - and their accounts of how she came to be living with them differ. Police found the girl, who recognises the name Maria, during a raid on the camp, in Farsala, central Greece, on Wednesday. She has now been taken into the care of a Greek charity called The Smile Of The Child, which has put out a Europe-wide alert. A statement from the charity said: "The features of the girl and the controversial claims of the persons who claimed to be the parents of the child led the authorities to collect a DNA sample test. The results of DNA testing proved that these people are not the biological parents of the child. The Smile of the Child in co-operation with national police authorities is taking all necessary steps to inform the competent actors at national and international level. The director The Smile Of The Child praised an observant prosecutor who went on the camp raid along with dozens of police. Costas Giannopoulos told Greece's Skai TV: "She saw a little blond head poking out from under the bedclothes. It struck her as odd, and that's how it all started. Apparently, the couple's various excuses included that the girl was found in a blanket and that she was handed to them by strangers. They later claimed she had a foreign father. Maria is described as: born around 2009, white, with blue eyes, long blonde hair, 100cm tall and weighing 17kg. The couple - a 39-year-old man and a 40-year-old woman - have been arrested and are now under investigation for abduction and falsifying identity and family certificates. The couple claimed to have a total 14 children, police said, and had registered different numbers with authorities in three different parts of Greece. Including Maria, the couple only actually had four. The woman is also said to have claimed to have given birth to six children within a space of less than 10 months. Police say they also found drugs and unregistered firearms in other parts of the camp, which is about 170 miles (280km) north of Athens. Officers are now working on the theory that, because of her appearance, Maria may be northern or eastern European. The case, which some people have likened to the Madeleine McCann disappearance, has raised concerns about how easy it appeared to be for people to get official documents for children who are not their own. A spokesman for Madeleine's family last night last night told the Daily Mirror newspaper: "This gives Kate and Gerry great hope that Madeleine could be found alive." The Smile Of The Child director Costas Giannopoulos said Maria was being examined by doctors. "We are shocked by how easy it is for people to register children as their own," he told the Greek TV station Skai. There is much more to investigate ... and I believe police will unravel a thread that doesn't just have to do with the girl. Greece has only acquired a central system of registration for births in the last five months.
