Demanding inquiry into the construction of a road, a man tried to consume poison outside Union road transport minister Nitin Gadkari's house here on Friday evening, police said.

Security personnel, however, stopped him in time, said an official of the Rana Pratap Nagar police station. Vijay Marotrao Pawar, resident of Mehkar in Maharashtra's Buldhana district, had written a letter two-three days ago demanding inquiry into the alleged substandard construction of the Shegaon-Khamgaon Palkhi road.
