Some people in the Waghoba Nagar slum colony were irked with Sudham Ranu Yadav (64) as he did not allow vehicles to pass through a road where the construction of a stable owned by him was underway, Kalwa police station senior inspector R D Malekar said.
Last night, a group of people reached the stable and fired from their revolvers at Yadav.
They also beat up other inmates of the stable in which Yadav's son Hariprasad was badly injured. He was later admitted in Kalwa's Chhatrapati Shivaji hospital.
