Karti Chidambaram Arrested: Corruption Or Vendetta?

This morning, as he landed in Chenani from London, Karti Chidambaram, the son of former Finance Minister P Chidambaram, was arrested by the CBI for not cooperating in a corruption probe against him. The CBI has accused Karti Chidambaram of taking bribes to help a big media company get illegal clearances for foreign investment by the finance ministry when his father was the minister back in 2007. It is a charge Karti Chidambaram denies. Is this corruption as the CBI says or is this vendetta, as the Congress claims?
