CBI chief Alok Verma today returned to his office in Delhi for the first time in three months, a day after he was reinstated by the Supreme Court, which scrapped an October government order divesting him of his powers and sending him on leave. He was received by M Nageswara Rao, who had been appointed interim chief in his place. Alok Verma's 10th floor office at the CBI headquarters had been sealed after he was sent on compulsory leave around 2 am on October 24 and replaced by Nageswar Rao, an additional director.
