LAS VEGAS — A private detective says Floyd Mayweather Jr. is posting a $100,000 reward for information about the theft of more than $7.2 million in jewelry from the boxer's Las Vegas home.

Investigator K.W. Hasan of Sherbrooke Jelan & Associates in Ellenwood, Ga., said Wednesday that he's sure someone knows who broke in while Mayweather was away.

Las Vegas police spokesman, Officer Jacinto Rivera, says Crime Stoppers of Nevada also has posted a $2,000 reward.

Police released a black-and-white security camera image of a man wearing glasses and a light-colored hooded sweat shirt.

Police say two or more burglars hit Mayweather's house at about 8:40 p.m. on Aug. 17.
