The Central Bureau of Investigation on Saturday carried out searches at the premises of former UP minister Anant Mishra in Lucknow and in Kanpur in connection with its probe in the National Rural Health Mission scam.
CBI teams seized some "incriminating" documents related to the NRHM from Mishra's premises,
sources said in New Delho.
The agency has already questioned Mishra twice in connection with the death of deputy chief medical officer Y S Sachan.
The CBI has registered 13 cases regarding alleged irregularities in the NRHM scam in Uttar Pradesh and is planning to register three new cases soon.
