Police seize phone of woman claiming to be Madeleine McCann ahead of new investigation

US investigators are taking a 'deep look' into the case

Dr Johansson told RadarOnline.com when Julia was in Poland, her phone was seized by police as part of a search and seizure, and that the 21-year-old had handed it over voluntarily.

According to reports, there is now a global probe into the case, with Orange County Sheriff's Department contacting Polish police.

Department Spokesman Sergeant Mike Woodroof told RadarOnline.com: “We are not going to make any comments about the case.

“Our investigation is taking a deep look into it and we’re going to let them do their investigative duties and then from that point let the judicial system take over – if it needs to.”

Since returning to Poland, Julia, has said she plans to take another DNA test and she does not believe the outcome of the first time. It suggested she was largely Polish, with some Lithuanian and Russian heritage.

Polish police have disputed her claims and her parents have said she is unwell and have repeatedly asked her to stop making the claims.

Last week Julia apologised to the McCanns in a 17-page statement, where she also said she might still be the missing girl.

She claimed she never said she was Madeleine - just that she believed she was. She apologised for creating an Instagram account with the nickname "I Am Madeleine McCann" and says she should have said, "Am I?"
