FALLS CHURCH, Va. (AP) — At least 170 reported sexual assaults — and possibly more — went uninvestigated by the D.C. police department between 2008 and 2011, according to a long-awaited report from a human rights group.

The 197-page report from New York-based Human Rights Watch also found a pattern of callous behavior by D.C. police toward sex assault victims, with many saying they were actively discouraged from pursuing a criminal case.
