Retired and undefeated boxing champ Floyd Mayweather Jr. was robbed of nearly $7 million in jewelry in August from his Las Vegas mansion.

According to a spokesman for Las Vegas Metro Police Department, the boxer's home was empty when intruders broke in, by smashing a window separating the master bedroom from the pool area, sometime between August 17th and August 18th.

There was security camera footage capture, but reports indicate that it was largely unusable aside from a grainy shot of one suspect was transformed into a still image by investigators.

Las Vegas detectives sent out a press release last week, seeking assistance from the public in solving the case, in which "four people forcefully entered a home in a gated community in the northwest part of the Las Vegas Valley, taking unique items."

The items stolen included a necklace and accompanying ruby-and-diamond encrusted boxing glove pendants, valued at $7 million.

Mayweather's camp has confirmed the burglary this week, announcing a $100,000 reward for information leading to recovery of the items. Only jewelry was taken, according to the announcement.

No one was hurt during the incident.
