Senior INLD leader Abhay Singh Chautala on Friday came to the defence of his party's state unit chief Nafe Singh Rathi, who has been booked in a suicide case, and alleged that the FIR has been lodged against him as part of a ''political conspiracy''. Chautala also demanded a CBI probe into the matter. Former Haryana minister Mange Ram Rathi's son Jagdish Rathi (55) allegedly committed suicide by consuming poison in Jhajjar's Bahadurgarh on Wednesday and six people, including Nafe Singh Rathi, have been booked under the charges of abetment, according to police. On December 26 last year, Jagdish Rathi had circulated an audio clip in which he had alleged that some people had been harassing him and if anything happens to him they would be responsible, police said. Chautala said the FIR has been lodged against Nafe Singh Rathi as part of a ''political conspiracy''. When the audio clip went viral on December 27, 2022, Nafe Singh Rathi had submitted an application to the police to get the matter investigated, the Ellenabad MP said. ''At that time, Jagdish was called to the police station and questioned by the SHO and the DSP. Jagdish went to the police station and gave a statement that he was under the influence of alcohol and did all this by mistake.
