Bathinda, Sept. 19 -- Four policemen, including Nandgarh station house officer (SHO) Ravinder Singh, were injured when a mob attacked the police team at Raike Kalan in Bathinda on Wednesday. According to the FIR, the police team had to open 15 rounds of fire from an assault rifle and a carbine in the air to disperse the violent mob trying to target a village youngster, identified as Sonu. Seven villagers, identified as Lovish, Rajan, Cheetoo, Laadi, Balwinder Babbu Singh, Pada and Gagi, were booked under Sections 109 (attempt to murder), 132 (assault on a public servant in the execution of his duty), and 118 (grievous hurt by dangerous weapons) of the Bharatiya Nyaya Sanhita (BNS). Police said that the SHO was attacked with a sharp-edged weapon on his arm and he was rushed to a private hospital in Bathinda. SSP Amneet Kondal visited the crime spot on Thursday morning and said some villagers had been rounded up for their involvement in the crime. SSP Kondal added that the SHO underwent plastic surgery after his veins were damaged in an attack by a sharp-edged weapon late last night. "Three accused named in the FIR had been arrested, and several others had been rounded up," she said. The district police have not revealed the identities of those held. A section of residents of Raike Kalan had organised a mela at a local dera. During the programme, a clash broke out between two groups. In the melee, a person identified as Sonu was chased by a mob, allegedly in an inebriated condition. Sonu rushed to the house of Balwinder Singh and the house owner locked the main door to protect youngster from the mob. Officials said that a police team from Nandgarh was already deployed at Raike Kalan to maintain law and order as a large congregation was expected to attend the annual fair. The situation turned grim when a group of villagers scaled the wall of Balwinder's house to gain access to Sonu, who was hiding inside. The mob attacked the house with stones, bricks and lathis. As the situation worsened, the police team led by SHO Ravinder Singh intervened to pacify the villagers. The FIR said that Lovish attacked the SHO with a sword and the police officer suffered serious injuries on his left arm. Later, the mob targeted a police vehicle and a private bus parked nearby....
