Nagpur, April 13 : A joint team of Central Bureau of Investigation(CBI)and Vigilance Department of Employees’ Provident Fund Organisation(EPFO) conducted searches at two EPFO offices in Nagpur city of Maharashtra, sources said here on Wednesday. The searches were conducted after receiving some complaints that some EPFO officials were giving favours to private firms. The Anti-Corruption Branch of CBI Nagpur and the EPFO’s vigilance team from Mumbai started the searches on Tuesday morning in the EPFO offices located at Tukdoji square and Umred road here and continued till late night, sources said. Sources further said a large number of files and PF entries of Provident Fund(PF)were checked by the joint teams during the searches. Besides, several documents have been seized, said sources . Pertinently filing of PF is compulsory for the company with more than 20 employees. The search team on Tuesday found that some EPFO officials had issued notices to schools and private companies, having more than 20 employees but no further action was taken in such cases.
