Former Minneapolis police officer Bradley Schnickel, accused of using social media to try to lure girls into sexual encounters, faces five new felony charges, including an allegation of having sex with a 16-year-old girl.

Seven alleged victims are mentioned in the charges filed Friday in Anoka County. That brings the number of girls accusing Schnickel of sending explicit messages and, in many cases, photos of his genitalia via Facebook and Skype to 20.

One of the charges filed Friday involves a Coon ­Rapids girl and dates back to 2010 — the oldest of the alleged online relationships involving Schnickel, 32. According to court documents, the girl, then 15, was roller blading in Coon Rapids in the summer of 2010 when she noticed a parked car and a male driver trying to get her attention. The man told her she was "sexy" and that he was 23, worked as a bartender and that his name was Brady, the charges say.

Authorities say the girl began interacting online though Facebook, Myspace, a webcam site with Yahoo and Tiny Chat with a man she believed was "Brady Schmidt," the same name other alleged victims say Schnickel used.

The girl told authorities that during the summer of 2011, when she was 16, she and Schnickel engaged in multiple acts of sexual intercourse and oral sex at a park and at her home in Coon Rapids, when her parents were away.

The court documents filed Friday also describe Schnickel as meeting with a 17-year-old girl near Life Time Fitness in Coon Rapids and touching her breasts. He allegedly told a 13-year-old he would get her alcohol in exchange for sex, asking for naked photos or her and where she lived.

Schnickel was previously charged with a number of counts of solicitation of other girls in Anoka and Hennepin counties. Those charges allege that he met a few of the girls with whom he communicated and had intercourse with one of them, a 14-year-old.

All but two of the alleged victims live in Anoka County; the others are from Brooklyn Center.

Some of the girls allegedly contacted by Schnickel online were preadolescent, prosecutor Paul Young said after Schnickel's last hearing ­earlier this month. Young also said that Schnickel used police equipment to locate some of his alleged victims.

Investigators have examined 9,000 printed Facebook pages of alleged victims, Anoka County authorities say.

Schnickel, who is married and has two young daughters, has been undergoing psychiatric evaluation, according to his attorney, Fred Bruno. Schnickel's last day on the Minneapolis police force was Feb. 8.
