Rohtak/Karnal, Nov. 10 -- Two men were killed and one was injured in separate incidents in Hisar and Karnal districts of Haryana amid disputes over bursting of firecrackers on Diwali night. In the first incident, a man was allegedly stabbed to death and his friend injured at a hotel in Barwala town of Hisar district on Sunday night. According to police, the deceased was identified as Mandeep Singh, 25. His injured friend, Naseeb, is undergoing treatment at the civil hospital in Barwala. Their third friend, Sachin, escaped unhurt. According to police, the three friends were staying in a hotel room and bursting firecrackers to celebrate Diwali when another group of youths staying at the hotel objected to it. This led to a heated argument, which soon escalated into a violent confrontation. During the clash, five youths allegedly attacked Mandeep with a knife. When Naseeb attempted to intervene, the assailants stabbed him as well, police said. On receiving information, police reached the spot and rushed the injured youths to the civil hospital, where doctors declared Mandeep dead. The police said they have registered a murder case against the accused and launched an investigation to identify and apprehend them. In another incident, a Bihar labourer was killed after a violent clash broke out between two groups of labourers at a rice mill in Karnal. The deceased was identified as Radheshyam, a migrant hailing from Darbhanga in Bihar. Police said that a group of men, including Rambharose, Akhilesh and others, attacked the victim under the influence of alcohol. Sources said both had a similar clash at least 10 days back, when the accused issued a death threat to Radheshyam. The police registered a murder case against Rambharose, Akhilesh, Ashwani, Lal Babu and others based on the complaint of the security guard, Ajay Kumar.
