Things changed overnight for A K Bassi, the investigating officer considered close to ousted CBI director Alok Verma, Bassi was a hero on Tuesday as he produced his colleague and Deputy Superintendent of Police, Devender Kumar, in a Delhi court, and to everyone's surprise even paraded him in front of the media. Kumar was arrested on the basis of an FIR registered against then CBI number two special director Rakesh Asthana. Kumar was sent to seven days' custody. However, Bassi's fate changed in less than 12 hours. After M Nageswar Rao was appointed the acting CBI chief on Tuesday night, one of his first orders was to transfer Bassi to Port Blair. Sources said Bassi was not even allowed to pick up his belongings from his cabin in the headquarters as it remained sealed for investigation and he walked out of the building refusing to answer questions from the media. “Sent to kalapani,” said one of his colleagues, alluding to a colonial prison in the Andaman and Nicobar Islands.
