The CBI has sent another summon to Trinamool Congress leader Binay Mishra's brother in a cattle smuggling case, officials said on Tuesday. Mr Mishra's brother has been summoned for interrogation on Wednesday, they said. The central probe agency had interrogated Mr Mishra's brother earlier. The Central Bureau of Investigation (CBI) named Bijay Mishra as a co accused in its supplementary chargesheet filed in the cattle-smuggling case last month. In its chargesheet filed before a special CBI court in West Bengal's Asansol, the agency had said Mr Mishra was missing.
