NEW DELHI: Aam Aadmi Party 's sacked minister Asim Ahmed Khan on Saturday evening claimed he was a victim of a conspiracy hatched by 'big' and 'small' leaders within the party.Denying that the voice in leaked audio clips of phone conversations was of any middleman as claimed, Khan alleged it was Shakil Ahmed, AAP's deputy Chief of minority wing, in the tape. "It is not the voice of any middleman but Shakil Ahmed's," Khan emphasised at a press conference in his palatial, two storey residence at Daryaganj.On his part, Ahmed has alleged threats to his life. "It is an open threat to me. Now that my name has been mentioned by him (Asif Ahmed Khan)," Ahmed told ET.The former minister said his public sacking came as a shock to him and, through the duration of Kejriwal's conference with media, he had been held by some AAP leaders. "I will tell you where I was between 3: 30 PM and 5:30 PM yesterday soon. I am collecting relevant evidence. In a day or two, I am going to make a big revelation about it. I don't want to say anything more because the proof could be tampered with if I said it prematurely," Khan told reporters.He also presented a local builder, Javed Khan, to the media. "Some of you have been going to his construction site and saying 'this was the place for which bribes were taken'. Ask him if I took money," the minister challenged reporters. He also asked the local builder, Javed Khan, what was his area of construction? Khan replied, "45 square yard." In the tapes released yesterday, the the areas being discussed differed between 120 and 200 square yards.When ET asked the builder if he was aware of anything said on tape by the ex-minister, he said, "I am not here to support Asimji. I just want to say that, reporters keep coming to my site and saying that this was the site...it is not true. Please stop doing this. We are living under fear."When ET checked with Shakil Ahmed, who was named by the sacked minister. Shakil did not deny nor confirm the specifics of the claims by Kejriwal or Ahmed. "An accused can say whatever he wishes to save himself. Let there be an investigation to decide if he is guilty or not," Ahmed told ET.Stunningly, Ahmed also said, he had asked Kejriwal "not to disclose" his name as the complainant of this alleged bribery. "But he released those audio tapes. I am afraid about my safety now. There is a threat to my life," he said.
