The body of the murdered teenager Scarlett Keeling was returned to Britain with her uterus, kidneys and stomach missing.
Scarlett's body is undergoing a third post mortem which has revealed her uterus, kidneys and stomach are missing.
Her mother Fiona MacKeown said that she did not give permission for the organs to be removed and is planning to return to India within the next two weeks to find out what has happened.
Scarlett was found on Anjuna beach, Goa on February 19.
Police initially said the 15-year-old died from accidental drowning but after pressure from Mrs MacKeown a second autopsy was carried out which revealed she was raped and killed.
Mrs MacKeown's lawyer, Vikram Varma, said there is no reason for the organs to be taken and they should not be removed without written permission.
"I have spoken to Fiona who has told me the uterus, kidneys and stomach are missing," he said.
"I am waiting for an email from the coroner confirming in writing what is missing so I can then take it up with the Ministry of Health.
"There is no reason to take these organs, a doctor only takes a sample of an organ for tests.
"To remove the whole organ without written consent is not permissible."
