Sangrur, April 23 -- Three motorcycle-borne men lobbed a petrol bomb at the house of a local jeweller in the Shivpuri area of Dhuri, police said on Wednesday. While no one was hurt, the bomb triggered a fire, causing damage to the main gate and a car. The complainant, Darshan Kumar, told police that he was asleep when he heard a blast in the courtyard around 10.53 pm on April 20. As he stepped out to examine the situation, he saw the porch, his car and a tarpaulin sheet on fire. Neighbours helped him extinguish the flames. Kumar said CCTV footage from the vicinity revealed three motorcycle-borne men arriving in the street and one of them tossing a petrol bomb into his house.
