Looks like an apology wasn't enough for Dani Mathers.

Days after the 29-year-old Playboy model body-shamed a naked woman at the gym through Snapchat, the Los Angeles Police Department has launched an official investigation into the incident, ET can confirm.

According to the LAPD, the identity of the woman Mathers photographed is still unknown, and that it was L.A. Fitness who filed the police report on Friday.

A law enforcement source confirms to ET that "the investigation is based on disseminating private images."

L.A. Fitness, where Mathers filmed the woman, told ET earlier on Friday that they would be contacting the police.

"Our written rules are very clear: Cell phone usage and photography are prohibited in the locker rooms. This is not only our rule, but common decency," a spokesperson for the gym said in a statement. "Her behavior is appalling and puts every member at risk of losing their privacy. Her membership has been permanently revoked, at all our health clubs, and law enforcement has been notified."

Mathers photographed the woman in a gym locker room, sending the nude photo out to her followers with the caption, "If I can't unsee this then you can't either."

The 2015 Playboy Playmate of the Year later apologized on Twitter, and through a series of apology videos on her Snapchat.

"Should never make light of another woman's naked body," she tweeted on Thursday. "I'm sorry for what I did… I need to take some time to myself now to reflect on why I did this horrible thing."

While LAPD's official investigation is on behalf of L.A. Fitness, should the victim come forward to file a report, Mathers could face a misdemeanor charge.

ET has reached out to Mathers for comment.
