Washington, Feb 21 : L. A police department is baffled as to how Rihanna's battered face photo taken after she was allegedly attacked leaked, and is currently investigating the case.

In the photograph, the `Umbrella' hitmaker can be seen with horrific injuries, including a split lip, a bloody nose, and wounds on her forehead and face.

It has been claimed that the photograph was taken after Rihanna was allegedly attacked by Chris Brown following a heated argument.

The L. A. P. D Officials have launched a probe to find whoever is responsible for the leak.

"The unauthorized release of a domestic violence photograph immediately generated an internal investigation. The Media Relations Section began receiving numerous enquiries about the release of a photograph associated with a domestic violence incident that occurred on February 8, 2009, involving entertainer Chris Brown. The photograph has the appearance of one taken during an official Domestic Violence investigation," Contactmusic quoted the L. A. P. D as saying.

"The Los Angeles Police Department takes seriously its duty to maintain the confidentiality of victims of domestic violence. The Department launched an immediate internal investigation and subsequently filed a personnel complaint. A violation of this type is considered serious misconduct, with penalties up to and including termination," the department stated further," the department added.

Meanwhile, Rihanna's father is said to be very upset with photo leak. (ANI)
