CBI sources said the agency has booked army officials and police personnel who were posted there when the incident took place in August 1998.
On November 22, 2012 Justice M H Attar of J-K High Court had ordered CBI inquiry into the extra-judicial killing in Surankote area of Poonch on a plea by families of the victims seeking a re-investigation.
On the intervening night of August 3 and 4, 1998, 19 persons -- six males and 13 females -- were killed at the house of Hassan Mohammad Sheikh at Sailan village in Surankote.
The police, in its FIR, had blamed foreign militants for carrying out the killings but an inquiry conducted by the State Human Rights Commission in October 1998 ruled out the involvement of militants.
The SHRC also recommended an inquiry into the case.
The families of the victims had filed a petition for re-investigation in the case before the High Court in 2011.
