CBI on Saturday conducted searches in the house of NCP MP Padamsinh Patil, arrested in connection with the murder of a senior Congress leader, at Osmanabad in Central Maharashtra.
Patil's elder son Jagatsinh Patil, a Minister with Maharashtra government, was asked to remain in the house during the searches, a senior CBI official said.
The details of the searches, which are still going on, were not available.
The CBI had last month also raided Patil's residence in South Mumbai and claimed to have recovered several firearms and incriminating documents.
The Lok Sabha MP from Osmanabad is currently lodged at Taloja jail in Navi Mumbai in connection with the murder of senior Congress leader Pawanraje Nimbalkar in June 2006.
