High drama unfolded in New Delhi late Wednesday as officers from India's equivalent of the FBI scaled the walls of a former finance minister's home to arrest him on corruption charges, local media reported. Earlier in the day, the Central Bureau of Investigation (CBI) had alerted airports to prevent Palaniappan Chidambaram, finance minister from 2004-2008 and again from 2012-2014, from leaving the country. Chidambaram, 73, earlier this week failed to secure bail and had not been seen since Tuesday, until he showed up at the headquarters of the opposition Congress party on Wednesday to proclaim his innocence.
