Surat: A 20-year-old history sheeter and his friend were murdered in cold blood near railway tracks in Udhna on Thursday late night over a past rift. Seven persons, who had attacked goon Ajay alias Sharad Patil and his friend Ravi Sharma (22), a commerce graduate, were detained by the police on Friday. Police said that on Thursday night, Patil, Sharma and a few of their friends were having food near the railway tracks when the group of seven accused arrived there. Patil and one of the accused named Dhama had a rift in the past and they had recently reached a settlement. However, when the group arrived near the railway tracks, Patil pulled out a knife and brandished at Dhama asking the latter why he was issuing threats to his friends. Dhama allegedly asked Patil to take it easy but when he did not back down, Dhama and his six accomplices attacked Patil and Sharma. According to police, Sharma was caught along with Patil in the melee while their other friends managed to escape. The attackers stabbed the duo mercilessly in their chest, throat, back and lower abdomen. “Both of them were stabbed over two dozen times,” said inspector M V Patel of Udhna police station. Later, when the duo’s friends arrived again, they found Patil and Sharma dead following which they informed their family members and police. Based on Sharma’s brother’s complaint, a murder case was registered against Dhama, Ajay Kaliyo, Mangal Kushwaha, Vicky Pandit, Narayan Udiyo, Mohan alias Mongiya Sonavane and Vishal Vasave. Police said that the attackers and the victims know each other as they all live in the same locality. “Patil was arrested in the past in an attempt to murder case by Limbayat police and there were half-a-dozen other cases of petty crimes registered against him,” Patel added.
