Junior Union Home Minister Ajay Mishra's son, accused in Lakhimpur Kheri case surrendered at a local court in Uttar Pradesh.
The Supreme Court had last week cancelled his bail and given him a week to surrender.
Jail Superintendent PP Singh said he will be kept in a separate barrack at the jail due to security reasons.
Ashish Mishra is accused of running over farmers with an SUV during a protest demonstration against the now-repealed contentious farm laws. He has been charged with the murder of farmers and a journalist after he allegedly ran over them with his vehicle.
He was granted bail by the Allahabad High Court in February this year. The Supreme Court last week cancelled his bail and has allowed him to approach the Allahabad High Court again.
Eight people died in Lakhimpur Kheri on October 3. After four farmers and a journalist were crushed by the convoy of the Union Minister's son, three more, including BJP workers, were killed in violence that broke out later.
The dead included four farmers and a journalist, who were mowed down allegedly by cars carrying BJP workers. The police had arrested Ashish in the case.
