The lawyer of the Unnao rape survivor died on Monday of complications from wounds suffered last year in a truck-car collision, blamed on a BJP leader, that also injured the girl and killed two of her aunts.

Mahendra Singh, under treatment for multi-organ damage at his Unnao home since being discharged from AIIMS, New Delhi, six months ago, died at the district hospital where he had been admitted on Sunday, his family said.

Kuldeep Sengar, a then MLA from the BJP who is serving a life term for kidnapping and raping the then minor girl in June 2017, is also accused of conspiracy in the murder case arising out of the truck-car collision.

After the July 28, 2019, collision on a Rae Bareli highway, the girl and Singh were admitted to AIIMS. While the girl recovered after a few months, the institute discharged Singh six months ago and advised home treatment.

After his rape conviction and sentencing by a Delhi court last December, Kuldeep was in March handed 10 years’ jail in the murder of the girl’s father in Unnao.

He had in April 2018 got the girl’s father beaten up for refusing to withdraw the rape case and implicated him in a false arms case. Days later, the father died of his injuries in Unnao jail.

The truck-collision murder case is pending with a Delhi court.

The Supreme Court had transferred all the three cases — relating to the rape and the murders of the survivor’s father and aunts – to Delhi and asked the CBI to probe them.

In August last year, the BJP had suspended Kuldeep from the party.
