Afzal, a resident of Gool, was the in-charge of the Sangaldan police post in the district.
"Notices have been issued to the BSF to send their nominal roll and... (make their men available) for questioning by the Special Investigation Team (SIT)," Ramban SSP Javaid Ahmed Matoo said.
The police want a list of BSF personnel deployed on patrolling duty and at the camp during the firing. Four people were killed when BSF men allegedly opened fire on the mob that was trying to barge into the security forces camp.
Mohammad Latif, a resident of Dalwah, had allegedly instigated the mob into attacking the camp by blaming security forces of having desecrated the holy Quran.
Latif's allegations had come after he was intercepted and questioned by a BSF patrolling party in the Daram belt of Gool tehsil.
Inspector general of BSF Rajeev Krishna has said that his personnel had opened fire in self-defence and with "maximum restraint" to quell the violence by the mob which had tried to storm their arms and ammunition store.
The state government has ordered a magisterial inquiry into the incident while Union home minister Sushil Kumar Shinde has initiated a probe into the role of BSF in the matter.
J&K chief minister Omar Abdullah had condemned the firing saying such incidents had the potential to jeopardise peace in the state.
