Lucknow, Jul 2 (IANS): A night after a gang rape survivor was attacked with acid here, the Uttar Pradesh Police are yet to arrest anyone. The victim has sustained burn injuries on the right side of her face and shoulder.

This was the fifth attack on the rape victim in the last nine years, police said.

The woman is admitted at the trauma centre of the King George's Medical University (KGMU) in Lucknow.

On Saturday night, she was going to take some water from a hand pump in the hostel at Aliganj area when she was attacked with acid.

Inspector General of Police Jai Narayan Singh said other hostel inmates rushed to her rescue when they heard her crying.

The inmates tried to trace the culprits but they had disappeared by then. The hostel has six feet high boundary walls.

On suspicion, police detained Bhondu Singh and Guddu, the two accused by the victim, but they were found to be in Rae Bareli at the time of the incident.

The 45-year-old was first gang raped in 2008 over some property dispute. In 2012, some people attacked her with a knife.

In 2013, acid was thrown at her again. In December last year, some people threatened to rape her daughter as well.

On March 23 this year, she was forced to drink acid on the Ganga-Gomti Express train when it was plying between Allahabad and Lucknow.

Uttar Pradesh Chief Minister Yogi Adityanath had gone to meet her at the hospital and assured her security. However, the ordeal for the woman continues.

A resident of Rae Bareli, Congress President Sonia Gandhi's Lok Sabha constituency, she works in a cafe run by acid attack survivors in Lucknow and lives in the hostel at Aliganj.
