Two women, Nilofar Jan, 22, and her sister-in-law Asiya Jan, 17, were raped and murdered in south Kashmir's Shopian district and their bodies were found by the side of a local stream outside the town on May 30.

Four police officers, including then district police chief, a deputy superintendent of police, an inspector and a sub-inspector, were suspended and later arrested by the government for negligence of duty and destruction of vital evidence in the case that triggered a public outrage across the Valley.

The high court had earlier ordered the DNA sampling and narco-analysis of the accused officers to unearth the truth about their involvement in the crime.

Chief Minister Omar Abdullah said Friday he would instruct the special investigating team (SIT) probing the crime to work round the clock before the case was taken over by the CBI.
