RJD leaders Tejashwi Yadav and Misa Bharti were detained by Bihar police on August 19 during a protest march toward the Raj Bhavan.
The protest was organized to demand accountability for recent paper leaks and police firing incidents in Siwan, with police using water cannons to disperse crowds.
The BJP dismissed the march as a failed political stunt, while RJD supporters continue to demand a high-level judicial inquiry into the recruitment scandals.
