The CBI has arrested two alleged conmen -- Ajit Kumar Patra and Minku Lal Jain -- who were running a "sophisticated impersonation and bribery racket" purportedly involving senior public servants and private individuals, officials said on Wednesday.

Patra, in connivance with Jain, impersonated high-ranking officials of various government departments, ministries, enforcement departments and judicial officers. They used false identities to gain undue favours in exchange for illegal gratification, a CBI spokesperson said in a statement.
