BSF today also claimed to have identified a 25-year-old local whose interception and questioning triggered the protests at its camp in Ramban.
BSF IG (Jammu Frontier) Rajeev Krishna said the BSF jawan sustained gun-shot wounds as the protesters pelted stones and tried to force their way.
Initial probe found Constable Ramhari of the force, who suffered a bullet injury in the stomach, was caught in the firing when he was returning to the BSF camp.
The force claimed Mohammed Latif, son of Mustafa and a resident of Dalwah in the area, instigated the mob leading to the situation where four people were killed and 44 others, including security personnel, were injured in stone-pelting and resultant firing.
Latif was intercepted in Daram belt of Gool tehsil and was questioned about his presence in the area.
