Rashtriya Janata Dal (RJD) strongman Mohammad Shahabuddin was brought to Delhi from Bihar's Siwan Jail on Sunday.
Shahabuddin will be taken to the Tihar Jail as per the Supreme Court's orders.
In the wee hours of Saturday morning, Shahabuddin was shifted from Siwan Jail to Patna amid tight security.
The criminal-turned-politician was escorted out of Siwan jail around 2:40am, flanked by security personnel and police.
However, despite the secretive efforts of the prison administration, supporters of Shahabuddin got wind of the developments and gathered outside the jail from midnight onwards to get a glimpse of their leader.
Carrying on with their operations, the Siwan administration escorted Shahabuddin to a white Tata Sumo, where he was lodged between two armed security officials.
