Lawrence was produced in court via video conferencing from the Ahmedabad  jail.The counsel of the accused, Harish Bhardwaj, said that witness Navneet Singh had stated in court that he neither knew nor recognised Lawrence Bishnoi.The police registered an attempt to murder case against Bishnoi and others after a clash took place at DAV College in Sector 10 in 2012 between two groups of student unions.The case was registered on the statement of Ankit Grover, a then BTech student at Chandigarh Engineering College, Landran. He told the police that he along with his friends Charandev Singh, Navneet Singh, Arasdeep and Jeevanjot Chahal went to Panjab University after Jeevanjot Chahal was announced as chairman of Panjab University Student Union (PUSU).On the same day, they went to DAV College, Sector 10, to attend a star night. He said a group of students, led by Lawrence Bishnoi and Amandeep Singh Multani, had entered from the back gate of the college after breaking the lock and attacked PUSU supporters who were making arrangements for a star night scheduled to be held in college.During the ruckus, the accused also opened fire and attacked  them with sharp weapons and sticks, injuring several students.The police registered a case against the accused under Sections 307 (attempt to murder), 148 and 149 (rioting), 452 (forcible entry), 323 and 325 (assault), and 506 (criminal intimidation) of the Indian Penal Code, as well as under Arms Act.
