Three months after Abhishek Kasliwal, the son of the owner of Sriram Mills, was arrested on charges of raping a middle-aged woman, the police has filed a chargesheet against him in a metropolitan magistrate court.

The chargesheet was filed on Thursday in the court of magistrate B Waghmare, police sources said, adding that investigations were over and trial is expected to begin in fast track court soon.

The 250-page chargesheet cites 15 witnesses, of whom three are eye witnesses. Among them are two watchmen of Sriram Mills who told police that they had seen Abhishek entering the mill with a woman in his car in late hours on March 11.

The chargesheet also contains the forensic reports, medical and chemical analysis reports of used condoms found in the car and reports of narco-analysis tests conducted on the accused in a Bangalore laboratory.

According to the police complaint lodged by the victim, Kasliwal had offered her a lift in his car in south Mumbai and promised to drop her at Bombay Central station. Instead he took her to Sriram Mills compound and raped her, the victim alleged.

The accused had denied the allegations of rape and said the victim was concocting the story. He was then subjected to lie detector tests.

Kasliwal (27) was granted bail on April 18 after a lower court rejected his plea twice. He was asked not to tamper with evidence and stay in Delhi until the chargesheet was filed.
