A three-year-old girl died after being used as a 'voodoo doll' by her mother's superstitious boss.

The child, who was also sexually assaulted, was taken to hospital in Kolkata, West Bengal in a critical condition on July 15.

Doctors found she had suffered multiple internal injuries — some of which were inflicted around her private parts, India Today reports.

'There are as many as seven needles forced into the child's body,' the hospital commented on her initial state.

The three-year-old's mother rushed the tragic youngster to hospital where medics discovered needles had been injected into her body during horrific 'black magic' abuse

'The needles could not be taken out as it may cause further damage to her body. She is kept under observation.'

The horrific abuse and torture she endured come to light after her mother took her to Bankura Medical College with a suspected fever.
