The sister of missing toddler Katrice Lee has hit out at a Real Housewives of Cheshire actress who confessed to posing as her sibling online.
Natasha Walker said she was stunned when she received a friend request from an account on Facebook claiming to be that of her missing sister.
Katrice disappeared on her second birthday on November 28, 1981, while at a supermarket with her mother Sharon on an Army base in Paderborn, Germany.
Almost four decades on, Katrice has not been found, despite a string of searches and an arrest being made last month in connection with the disappearance.
However, Mrs Walker, 45, has been plagued by heartless people impersonating her sister which she said has had a 'horrific' effect on her mental health.
Appearing at Wirral Magistrates' Court, Heidi Robinson this week admitted sending the friend request and claiming she was Katrice in November last year.
The 40-year-old today apologised to Mrs Walker and her family, adding she had been suffering with psychosis and had actually believed she was Katrice.
But Mrs Walker hit out at Robinson after a judge adjourned the case until October 30 for a pre-sentence report to be prepared.
Katrice's sister said: 'I am relieved she has finally admitted guilt.
'I have put in a formal complaint to the police as I feel I have been treated disgustingly. It appears that if you commit a crime you are better supported.
'The impact this has had on my mental health has been pretty horrific. My feelings have never been taken into consideration.'
Katrice disappeared while on a shopping trip to the NAAFI to buy food for her birthday party.
Her family have been critical of a string of failings by the Royal Military Police, who did not notify local hospitals of an eye condition the toddler had and only treated the case as a missing person inquiry.
In 2012, the Ministry of Defence apologised for its 'flawed investigations' and a review team was appointed to reassess the case.
Speaking after her court case was adjourned, Robinson, of Moreton, Merseyside, apologised to Katrice's family for the pain she had caused them.
She said: 'I actually believed completely that I was Katrice. I'd had mental health issues leading up to the situation.
'I was then at the time experiencing what I now know to be psychosis.
'I really didn't intend to hurt the family but as I know my actions have done that, I am deeply sorry and that is why I have pleaded guilty.
'I am now getting help and I apologise sincerely to the Lee family and my family.'
Last month, military police arrested and released without charge an ex-serviceman in connection with her disappearance and began searching a house in Swindon.
