A metal rod that was drilling an underground tunnel for power cables in Madhyamgram veered off its course, barrelled up and pierced through a first-floor room of a double-storey building around 2.30am on Wednesday.
A quake-like tremor jolted the residents of the house in the Rani Park area of Madhyamgram, on the northern fringes, out of their sleep when the rod perforated the walls. No one was injured.
Rahul Chakrabarty, the owner of the house, said the building was damaged beyond repair. “I am not sure whether it is safe to stay here any longer,” he said.
