Scarlett Keeling was found on Anjuna beach in February and police initially said the 15-year-old died from accidental drowning.

Her mother Fiona MacKeown maintained her daughter was attacked and a second autopsy was carried out which revealed she was raped and killed.

Her body was brought back to the UK for a third post mortem examination which revealed her uterus, kidneys and stomach are missing.

Fiona MacKeown said permission was never given for the entire organs to be removed and is due to arrive in Goa on Saturday evening.

Her lawyer, Vikram Varma, said she will also be speaking to the Indian Central Bureau of Investigation (CBI) who are to take over the case.

Nerlon Albuquerque, the police officer who first investigated the death, was dismissed earlier this month.

Following the second post-mortem examination, detectives said Scarlett was given Ecstasy, cocaine and LSD on the night she died.

They have arrested two men, Samson D'Souza, 28, who was remanded in custody on suspicion of rape, and Placido Carvalho, aged between 30 and 35, who has appeared in court on suspicion of drugging Scarlett and assisting in the murder by that act.

Mrs MacKeown, 43, from Bradworthy, north Devon, has claimed that links between police officials, politicians and the drugs mafia have hampered a proper investigation.
