LOS ANGELES (AP) — Two Los Angeles police officers won't face criminal charges alleging they leaked a photo of pop star Rihanna's bruised and beaten face after she was assaulted by singer Chris Brown, the Los Angeles County district attorney's office said.

An internal report by prosecutors says that after a three-year investigation, they didn't have enough evidence to show celebrity news website TMZ paid the accused officers for the photo, and that became an obstacle in charging them.

The Associated Press report obtained a copy of the March 28 report on Thursday after its contents were first reported by the Los Angeles Times.
