KOLKATA, July 21 -- Nishu Khan, one of the nine people held from Kolkata and its adjacent New Town area on Saturday by state STF and Bihar police teams, claimed before the media on Sunday that "his brother" Tauseef Raza alias Tauseef Badshah got involved in the July 17 murder of gangster Chandan Mishra inside a hospital in Patna "out of ignorance." Khan claimed that the gang members drove to Kolkata in his car after killing Mishra and Taushif drove the vehicle.In the hospital's security camera footage, Taushif was found to be leading the team of five hitmen all of whom have been arrested. "I met Tauseef in Patna's Beur jail two years ago and we became good friends. He is my brother. I kept telling him not to get involved in any wrong activity. I told him repeatedly not to bring bad names to his family. Yet, he got involved out of ignorance," Nishu Khan told the media when was taken to Kolkata's Alipore court on Sunday afternoon. "Tauseef surrendered to the Bihar police before the raids. He was on his way back to Patna when it happened," Khan said. At the court, the Bihar police prayed for transit remand for four other men alleged to be directly involved in Mishra's murder inside Patna's Paras Hospital. The court granted the remand. No Bihar or state police officer talked to the media about the case. Khan talked to reporters while lying inside an ambulance parked inside the court premises. He said he was shot in the leg in 2023 and was incapable of walking. "After the murder, I advised Taushif to surrender. I don't know why Chandan Mishra was killed. It is a false allegation that the murder was planned at my home. I wasn't there," Khan said. Khan claimed that gangster Omkarnath Singh alias Sheru Singh - who is currently lodged at Benga's Purulia correctional home in connection with a 2023 jewellery showroom robbery and is suspected to have ordered Mishra's murder - was earlier a friend of the victim. Khan added, "We were about to leave for Delhi when we were arrested. We came to Kolkata in my car from Patna." A state police officer said the raids were conducted after the Bihar police team visited the Purulia correctional home and questioned Sheru Singh. The officer also claimed the Bihar police team took Taushif into custody before the raids....
