Shailendra and Sachin, sons of Radheyshayam Jaiswal, an MLA from Sitapur Sadar, shot at Krishnapal after a heated debate over ownership of 18 'Bigha' land on Dhanipur village, sources said.
Krishnapal, who sustained injury on one leg, was rushed to District hospital by the police, which, however, did not registered his complain.
On the other hand police booked Krishnapal.
Later, his family members and villagers blocked NH-24 demanding immediate action against culprits, sources said.
Family members claimed that the land belonged to Krishnapal but two month ago it was forcibly grabbed by the MLA.
