"The girl, a class IX student, was attacked by three youths on Monday, who also allegedly molested and tore her clothes apart," said Satish Kumar, Inspector of Civil Lines police station.
The girl managed to escape and filed a complaint with the Civil Lines police station, Kumar said.
Later, the three youths were also arrested.
However, the case took a turn for worse when a news item purportedly carrying a picture of the girl was published in Hindi daily.
According to the family, the girl felt so embarrassed by the report that she put herself on fire.
"A local Hindi daily carried a news item about the incident. The girl, who was apparently upset over it, set herself ablaze," said Kumar.
With 90 per cent burn injuries, she was admitted to a government hospital here on Wednesday, and later she was referred to Safdarjung hospital in Delhi.
