All the family members had gathered to perform puja in memory of the elders last night and as they were having dinner, Ashwin, son of a mine owner, and his cousins - Vinod and Manoj - quarreled over a trivial issue, police said.
Ashwin, in an inebriated state, allegedly opened fire at them, police said.
Manoj sustained injury in the thigh, while another bullet pierced Vinod's abdomen and also hit the left arm of another person Ranjit, police said.
All are undergoing treatment at a hospital here and are said to be out of danger. Additional SP Vijay Dambal and Dy SP Suresh visited the spot.
