The Camden County Prosecutor's Office said 44-year-old Jeffrey M. Tyther, of Voorhees, is facing a number of charges after the incident.
The prosecutor said this all began back in September as Tyther was on-duty in a marked police cruiser. He pulled up next to the woman and waved at her, investigators said.
Then, Tyther allegedly used the State Police NCIC motor vehicle database to obtain information about the woman.
According to the prosecutor's office, use of that database is specifically limited to law enforcement purposes only, meaning it can only be used to further a criminal investigation.
The woman involved was not suspect of any crimes or motor vehicle violations, the prosecutor said, meaning Tyther had no reason to look up her information in that database.
Tyther is further accused of using that woman's personal information to find her on Facebook. He attempted to "friend" her within a few days of seeing her on the road, the prosecutor said, but when she didn't respond to the friend request Tyther allegedly emailed her, identifying himself as the officer who waved at her earlier that week.
The woman told a coworker about the incident and the coworker contacted police, the prosecutor said.
Tyther is charged with Computer Theft, a 2nd degree charge, and Violating the Motor Vehicle Record Law, a 4th degree offense. He turned himself in to the State Police Monday and was released on a summons.
Tyther was suspended without pay from the Voorhees Police Department Saturday.
