The family and the lawyer of Ishrat Jahan, who was killed in an alleged fake encounter in Gujarat, today raised questions over David Coleman Headley's testimony that she was an LeT operative, saying this was for the "political benefit of some big people" whose names have been "besmirched."

Musarrat, the sister of the 19-year-old college girl, and lawyer Vrinda Grover claimed that she had no terror links, hours after the Pakistani-American terrorist's deposition in a special court over a videolink from the US in the 26/11 case.

Grover also questioned prosecutor Ujjwal Nikam's tactics in the special court here, saying certain questions put to Headley by him had nothing to do with the Mumbai attack case and alleged they can have a "political relevance."

Musarrat expressed surprise over the claim made by Headley and said investigations have proved she was innocent but killed in a "fake encounter".

"It has been proved in investigations that it was a fake encounter. We are not saying this, it has been proved by the Indian investigators that my sister, Ishrat, was innocent. She was killed...it was a fake encounter and a political conspiracy," she said in Mumbai.

"Many big people are involved in it. Headley is saying all this because they will benefit politically out of it. I don't understand that despite investigations, which has proved she was innocent, why judgement in the case is taking so long. He himself (Headley) is a terrorist and is in jail in the US, how does his statement counts?" she asked.

"There are big people involved in this fake encounter I do not want to take any names. All I want to day is that what others say does not matter.

"We are fighting a legal battle for past 11 years and it has been proved that it was a fake encounter. What Headley is saying, I don't care. All I know and concerned is that my sister was innocent. We don't agree to what others say.

Ishrat's uncle Rauf Lala regretted that attempts were being made to link Ishrat's name with terror from Headley's testimony.

"This is just a ploy by those guilty who are powerful to try and salvage their names that have been besmirched," said Ishrat's mother Shamima Kausar.

Grover said she was surprised how suddenly the name of Ishrat Jehan was brought up by the prosecutor.

"They can have a political relevance, but they can have no relevance to 26/11. The public prosecutor in a procedure which is wrong and illegal in law gives a multiple choice question to a witness and says 'now I will give you three names(of female LeT suicide bombers that included Ishrat Jehan) you select one name which will be that female person," she said.

Grover said "the prosecutor gives three multiple choices and he says 'Noor Jahan Begum, Ishrat Jahan and Mumtaz Begum'. He(Headley) selects Ishrat Jahan. This is double hearsay and he is saying I have no personal knowledge," she added.

"It is not evidence. It is all mockery pointing to a conspiracy. There may be politics," she said.

Grover maintained that Headley in his testimony had said he only heard about a "botched-up" operation and that he did not know of any female sucide bomber.
