NT ICAC launches Rolfe investigation

Following a five-week trial in Darwin, Const Rolfe, 30, was found not guilty on March 11 of murdering Kumanjayi Walker, 19, on November 9, 2019.

After he was acquitted the NT Police Association, Opposition politicians and Const Rolfe's legal team alleged political interference may have affected the decision to prosecute the constable.

Chief Minister Michael Gunner and Police Commissioner Jamie Chalker have denied the allegations.

"My investigation will focus upon the period between the shooting incident and the presentation of Mr Rolfe for charging," Mr Riches said on Tuesday.

The commissioner said he may hold a public inquiry to hear some witnesses.
