"Sloppy work on their part," says Ronald Fenty, speaking to PEOPLE via telephone from Barbados Friday, shortly after the emergence of a graphic photo Thursday reportedly showing Rihanna's injuries from the alleged assault by boyfriend Chris Brown.
The picture is a close-up of a young woman with her eyes closed, bruises on her forehead, and cuts on her lips and cheeks. Because of the nature of the case, PEOPLE has chosen not to post the photo.
The Los Angeles Police Department issued a statement asking for the public to help with "information concerning the unauthorized release of the photograph."
"A violation of this type is considered serious misconduct, with penalties up to and including termination," police said.
Brown, 19, who released a statement saying he is "sorry and saddened," was arrested on a felony criminal threat charge Feb. 8. His case has not yet been presented by police to prosecutors.
Rihanna Turns 21Today is the "Umbrella" singer's 21st birthday, but Fenty says he's not sure how his daughter – who has not been seen in public since the alleged attack hours before the Grammy Awards – plans to spend her special day.
"There's no party that I know of," he says.
