The Supreme Court will next week hear a plea by Alwar lynching victim Rakbar Khan's family, who sought a court-monitored probe on Monday.
The plea also sought transfer of the trial out of Rajasthan.
On September 7, the Alwar police charged three men linked to the murder of Rakbar Khan.
"A 25-page chargesheet along with supporting documents have been submitted before Additional Chief Judicial Magistrate Court, Ramgarh in which three have been charged with murder. The probe is on, under our supervision at the ACJM court," deputy superintendent of police Ashok Chauhan said.
The role of the police in the entire incident was also under the scanner after they reportedly made a delay of three hours in taking the 28-year-old victim to the hospital.
Rakbar Khan, a resident of Haryana and his friend Aslam, were transporting two cows to Kolgaon through a forest area on July 21 when a mob attacked them allegedly presuming they were taking the animals for slaughter.
While Aslam managed to escape, Rakbar Khan died after the mob thrashed him.
