The Supreme Court Tuesday said it would set up a bench to hear on Wednesday a plea challenging the grant of bail by the Allahabad High Court to Ashish Mishra, son of Union minister Ajay Mishra, in connection with the Lakhimpur Kheri violence that left eight people, including four farmers, dead.

A bench headed by Chief Justice N V Ramana took note of the submission of lawyer Prashant Bhushan, appearing for some farmers, that there was an attack on one of the prime witnesses of the case.
