Police in Malta are investigating two more possible sightings on the island of missing Madeleine McCann.
The search for Madeleine has been taken to Malta
A spokeswoman said a British man and a local woman had told officers they may have seen the British four-year-old.
It follows a number of other reported sightings of a child resembling Madeleine in the island's capital, Valletta, and five other locations.
Madeleine disappeared from the holiday apartment where she was staying in Praia De Luz, Portugal, on 3 May.
Detectives in Malta are following up claims by a Maltese woman who said she had seen a "look-alike" of Madeleine accompanied by a middle-aged woman near the City Gate in Valletta.
A British man staying in Malta also reported to officers that he had seen a girl matching Madeleine's description with a woman of either Spanish or Arabic origin.
"So far, police investigations have yielded negative results," a police spokeswoman said. "Nevertheless, the police will continue investigating this case."
Detectives in Malta have been looking into other possible sightings of Madeleine since 27 May.
Ray Roberts, from Anglesey, north Wales, told police he had seen a child in Sliema wearing what looked like a black wig and being told "Get up, little girl" by a man of Arab appearance.
And others have reported seeing a child resembling Madeleine in Valletta, the resort of St Paul's Bay, the towns of Sliema, Mdina Marsascala and the village of Bahar-ic-Caghaq.
But none of the reported sightings has yet yielded any further information on her whereabouts.
The McCanns say they aim to ensure Madeleine is not forgotten
A spokesman for Madeleine's parents, Gerry and Kate McCann, earlier said they were not giving credence to the claims of sightings.
Instead, the couple, from Rothley in Leicestershire, are focusing their efforts on their campaign to find her.
On Friday balloons were released all over the world, to mark the 50th day since Madeleine went missing.
A message from the McCanns on the website said: "The objective is simple - after seven weeks missing, we must continue to ensure she is not forgotten."
The couple say they want to refocus attention away from themselves and back on the hunt for their daughter. They also want to highlight the cases of other missing children.
A paid campaign manager has been selected to head the team following interviews in the UK attended by Mr McCann. The appointment will be confirmed next week.
