New Delhi: Twelve days before his retirement, CBI Director Ranjit Sinha today suffered a major blow when the Supreme Court removed him from the 2G scam case, saying the allegations against him of protecting some accused appears to be "prima facie credible"

An apex court bench of Chief Justice H.L. Dattu, Justive Madan B. Lokur and Justice A.K. Sikri said that the senior-most officer heading the investigation team probing the 2G case will take over the overall investigations of the 2G cases.
