Lucknow: The CBI on Monday arrested two persons including a Congress leader and transport contractor Daljeet Singh in connection with the public distribution system scam in which foodgrains meant for poor were allegedly diverted to neighbouring countries.

Complainant Vishwanath Chaturvedi had last month claimed before the Supreme Court that CBI was not taking action against Singh because of his links with the Congress party and state Congress chief.

The CBI alleged that Singh was kingpin of scam and his trucks were allegedly used to divert food grains from FCI and UP Food Corporation godowns during 2004-06, they said.

The CBI, which registered the case in 2010, had carried out searches at 12 location in Lucknow on April 21.

The agency is probing the case in five districts while the rest of the districts are being probed by state police.

The CBI took over the probe after the Allahabad High Court on December 3, 2010, asked it to take over the case in Gonda, Lucknow, Varanasi, Ballia, Lakhimpur and Sitapur districts.
