Julia Wandelt is on trial accused of targeting McCann family in a two-and-a-half-year harassment campaign

Madeleine McCann’s brother and sister have described being stressed and scared by their “creepy” and “deeply disturbing” interactions with an alleged stalker who claimed to be their missing sister.

Giving evidence at the trial of Julia Wandelt, 24, who stands accused of targeting the family in a two-and-a-half-year harassment campaign, the twins Amelie and Sean McCann recalled the defendant contacting them a number of times saying she was Madeleine, who disappeared during a family holiday in Portugal in 2007 when she was three and they were two.

Appearing via video link, Amelie said the persistence of Wandelt, a Polish national, in contacting her on various social media platforms and writing letters to her home was “quite scary because you don’t know what she’ll do next”.

Messages to her from Wandelt were read to the court in which the alleged stalker described memories of being in the McCann household that she said had been recovered under hypnosis.
