Indian police are expected to formally charge five of six suspects with murder in the death of 23-year-old woman who was raped on a moving bus in New Delhi.
The sixth suspect is under 18 and a juvenile.
A police officer says they have ordered a bone test for the sixth accused to confirm his age. He spoke on condition of anonymity as he was not authorised to talk to reporters.
Under Indian law, a juvenile cannot be prosecuted for murder.
New Delhi police spokesman Rajan Bhagat said on Tuesday that a charge-sheet in the case will be filed in court on Thursday.
The physiotherapy student died in a Singapore hospital where she had been sent for emergency treatment after the crime in India’s capital on December 16.
