Rajasthan chief minister Ashok Gehlot on Friday ordered a fresh investigation into the 2017 Pehlu Khan lynching case and decided to follow it up with an appeal against the acquittal of all six accused in the case by an Alwar court two days ago.

The chief minister also set up a special investigation team under the supervision of state's additional director-general of police (crime) and decided to hire a senior lawyer to guide the probe, besides preparing grounds for appeal in the case.

The chief minister took the decision in a high-level review meeting held for examining the shortcomings in the probe and the findings of the court, said an official statement.

The SIT, set up on the chief minister's order, will submit its report within 15 days, the statement added.

The chief minister's decision followed two days after an Alwar court acquitted all six persons, accused of leading a mob of suspected cow vigilantes to attack and lynch 55-year-old Pehlu Khan, a dairy farmer from the Nuh district of Haryana. Khan was lynched near Alwar while returning home after buying cattle from Rajasthan.

The Alwar court on Wednesday acquitted all six adult accused in the case, giving them the benefit of doubt. Three other juveniles allegedly involved in the case are facing inquiry by a juvenile justice board.
