New Delhi, Oct 10 (IANS): Gangster Sunil Rathi claimed before a Delhi Court on Thursday that the police conducted a "false" and "biased" investigation against him in an alleged murder case.

"A false challan was prepared against me after conducting a biased and unfair probe," said Rathi while recording statement before Additional Sessions Judge Kamini Lau.

Rathi denied the allegation of threatening the complainant's family and said he had been falsely implicated in the case.

Rathi, along with other accused, allegedly killed Radhey Shyam, Superintending Engineer of the UP Irrigation Department, on June 18, 2006. Shyam was looking after the Rs 240 crore Upper Ganga Link Canal project, under which Ganga and Yamuna rivers were to be linked to solve the irrigation and drinking water problems.

He was allegedly killed due to a clash with another engineer over the project.

The case was transferred from Roorkee in Uttarakhand to Delhi in 2011 on the Supreme Court's order due to continuous threats to the victim's family to prevent them from deposing in the court.

Rathi had allegedly killed Bajrangi at Baghpat Jail on July 9, 2018.
