The accused used to beat his sister and on May 16, 2016, he put his sister's hand on a hot gas burner, causing burn injuries to her, the prosecution said.
The girl called up a child helpline number on May 19, 2016 and subsequently went to police along with a social worker and lodged a complaint against her brother.
The accused was booked under IPC sections 354A(1)(ii) (sexual harassment) and 323 (voluntarily causing hurt), and relevant provisions of the Protection of Children from Sexual Offences (POCSO)Act.
The judge said the victim, with the help of an NGO, lodged a complaint against her brother, but neither she nor her mother supported the prosecution story in the court.

There is no corroboration of the complaint and no other independent witness has been examined by the prosecution, she observed.
"In the absence of any evidence on part of the complainant, it is difficult for me to hold the accused guilty. Hence, I come to the conclusion that the prosecution has failed to prove the guilt of the accused beyond all reasonable doubt," the judge said in her order.
