An Anchorage police officer has been accused of sexually assaulting multiple women while he was on duty.

Anthony Rollins, a 13-year veteran and former department spokesman, was indicted by a grand jury and arrested Wednesday. He's being held on a $100,000 cash only bond.

He's been charged with four counts of first-degree sexual assault, six counts of second-degree assault, four counts of criminal use of a computer and six counts of official misconduct.

A local group that supports victims of sexual assault brought one woman's allegations to the police department's attention. Officials said at a news conference that police then began investigation Rollins' past contact with women, and found five more alleged victims.
