Police in Los Angeles are investigating whether the eye patch Rihanna wore as an accessory last year was used to cover evidence of domestic abuse at the hands of ex-boyfriend Chris Brown.

The “Umbrella” star was said to have scratched her cornea in 2008 and covered her eye for a while when she debuted a diamond-encrusted patch at the American Music Awards last November.

Los Angeles police are looking into possible past instances of abuse involving the star following last weekend’s arrest of Brown on charges of physically attacking Rihanna.

LAPD officers are speaking with management and friends, who say the Rihanna has previously had mysterious injuries which she refused to explain.

“We’re investigating if her eye injury could have been caused by Brown,” a police source told The Sun. “There could be an innocent explanation, but police believe Rihanna has previously refused to make a complaint against Brown.”

“She is now being asked about her past injuries and is beginning to open up about incidents in their relationship.”
