A woman falsely claimed a Pennsylvania police officer sexually assaulted her because she was angry he didn't return 102 text messages after a hotel tryst, police said.

The officer, Mike Foley, resigned from the North Braddock police force on July 18 after someone posted an online sex ad picturing him and asking women if they fantasized about being with a cop. Foley has denied placing the ad, and the woman charged Monday with falsely accusing him of sexual assault has not been linked to it either.

Cranberry Township police said in a criminal complaint that the woman, Michelle Milliron, filed false police reports the day after Foley resigned because she was angry that he repeatedly ignored her following their sexual encounter on April 12.

Cranberry police never charged Foley with a crime because they discovered he and Milliron exchanged "very explicit" text messages and nude photos indicating they planned to meet for sex, the complaint said.

Online court records don't list an attorney for Milliron, who faces a preliminary hearing on Sept. 29 on charges of false reports and making a false unsworn statement to authorities, misdemeanors each carrying a maximum two-year prison term upon conviction, KDKA TV reports.
