The 22-year-old BSc student of Guru Kashi University, a private institute, in Talwandi Sabo, is battling for life at All India Institute of Medical Sciences (AIIMS), Bathinda. SSP Amneet Kondal said on Thursday that Manpreet Singh, Mangu Singh, Manpreet Singh alias Mana, and Khushpreet Singh have been arrested, while teams have been constituted to arrest Dilpreet Singh and Lovepeet Singh. SSP said a look-out circular (LOC) was issued against Dilpreet today, and efforts are on to find if more persons were involved in the crime. She said that Leeroy suffered critical head injuries, and he is under constant medical observation. Ruling out the hate crime angle, the SSP said that the attack followed an argument between Leeroy and the university security guard, Dilpreet Singh. "During checking at the university gate on August 12, a baseball bat was found in Leeroy's car, and he had an argument with Dilpreet. A day later, Dilpreet and his accomplices followed Leeroy and attacked him with baseball bats, sticks, and sharp-edged weapons. Leeroy is in a critical condition," the SSP said.
