"Sloppy work on their part," Fenty reportedly told the magazine from Barbados on Friday (February 20).
Fenty also spoke with UsMagazine.com on Friday, describing the photo as "terrible."
"Yeah, I saw it," he told the magazine. "It's disturbing."
He added that he thought people now will be able to "grasp the situation a lot better. It's good and it's bad to see the picture because there's other people who were thinking differently, that [Rihanna's injuries] may not be that bad, just a little spank or a little thing."
The photo appeared online Thursday night, and immediately prompted an internal LAPD investigation into the leak.
"The unauthorized release of a domestic-violence photograph immediately generated an internal investigation," an LAPD spokesman said in statement about the photo. "The Los Angeles Police Department Media Relations Section began receiving numerous inquiries about the release of a photograph associated with a domestic violence incident that occurred on February 8, 2009, involving entertainer Chris Brown."
Although it does not officially confirm that the woman in the photo is Rihanna, the statement continues, "The photograph appeared on an entertainment website. The photograph has the appearance of one taken during an official Domestic Violence investigation."
According to CNN, the chief investigator in the case said that the department has tried to guard against leaks. Detective Deshon Andrews told CNN that he has been keeping the case file guarded and no copies had been made of the original photos and documents.
"The Los Angeles Police Department takes seriously its duty to maintain the confidentiality of victims of domestic violence," the LAPD asserted in the statement. "A violation of this type is considered serious misconduct, with penalties up to and including termination."
The photo has caused considerable controversy with fans.
Rihanna's father spoke with People.com last week, saying, "At some point, she will speak out," adding, "I hope she will stand up for women all over the world."
Brown, 19, who released a statement Saturday saying he is "sorry and saddened," was arrested on a felony criminal threat charge on February 8. His case has not yet been presented by police to prosecutors.
