Four-time Lok Sabha MP and Jan Adhikar Party (Loktantrik) President Pappu Yadav has levelled sensational allegations on the nexus of corrupt officials, politicians and mafia in Bihar who may be involved in the murder of IndiGo Airlines manager Rupesh Kumar Singh.

"Five days since the incident, there is no headway into the investigation of Rupesh Singh's murder and it indicates a nexus of corrupt officials, leaders and land, sand and liquor mafia," Yadav said.
