Patna, Aug. 1: A Central Board of Investigation team from New Delhi raided jailed Mokama MLA Anant Singh's residence this morning.

The team entered the MLA's 1 Mall Road residence around 6am and left, according to sources, with documents and a laptop at 2pm.

Following the raid, the CBI lodged a case against the MLA's construction company, Raj Nandini Pvt Ltd.

Patna senior superintendent of police Vikas Vaibhav confirmed the operation. He said: "The CBI team requested Patna police for assistance. They requested Sachivalaya police station's help during the search operation at the MLA's house."

A lot of details is not available on the CBI operation but it could increase troubles of the incarcerated legislator who is already under heat over several cases.

On June 24, officers had arrested Singh from his residence after a raid for illegal possession of ammunition and also in connection with a kidnapping case lodged against him in Bihta last year. After being sent to judicial custody, the police confirmed he was involved in another kidnapping and murder case lodged with Barh police station area on June 17. The Enforcement Directorate (ED), too, has started an investigation against the MLA.

On the CBI raid, a source said: "Though details of the CBI raid today are still unclear, they are said to have confiscated some documents and also a laptop from his house. Earlier on July 2, the CBI, along with vigilance sleuths, had raided the NTPC unit in Barh, following complaints of largescale corruption and discrepancies in awarding of contracts to particular firms. Anant Singh's name cropped up in this case too."

An officer said: "Troubles for Anant Singh are on the rise. The police, the ED and now the CBI, all are after him."
