The CBI on Monday said it was questioning persons concerned in connection with its investigation into Uttar Pradesh's illegal sand mining case.
"The team is completing the field investigation. And the private persons and government officials associated with the case are being examined," the source said.
The CBI had registered separate cases into the alleged irregularities in grant of licences between 2012 and 2016, in violation of the Allahabad High Court order which had ratified an e-tender policy in Kaushambi and Shamli districts in 2018.
