Indrani's driver says he doesn't know content of his letter to

Shyamvar Rai, a former driver of Indrani Mukerjea, the prime accused in the Sheena Bora murder case, today said he did not know the content of his letter written to the court last year.
The letter requested the court to make him an approver -- accused-turned-prosecution witness -- in the sensational case. The court had granted the request.
During his examination by the prosecution, Rai last week narrated how Sheena, Indrani's daughter, was murdered.
During the cross-examination by defence lawyers today, when shown the letter, he said he can not read English, and hence did not know its content, though the signature was his.

The letter was purportedly written on Rai's behalf.
Rai also told the court today that he was not aware of the legal provisions relating to approvers.

He said he was also not aware that after becoming an approver he would be pardoned by the court.
According to the CBI, Indrani and her former husband Sanjeev Khanna strangled Sheena, Indrani's daughter from an earlier relationship, inside a car here in April 2012. Rai was driving the car.
The murder came to light in August 2015 after Rai, arrested in another case, spilled the beans. Later, Indrani's husband Peter Mukerjea, a former media baron, was also arrested for being party to the conspiracy.

The CBI claimed that financial dispute was behind the killing. Also, Sheena was in a relationship with Peter's son from earlier marriage, which Indrani did not approve of, it said.
