Burglars hit tennis star Venus Williams' Florida home, stealing $400,000 worth of goods while she was at the U.S. Open, police said Thursday.

The burglary happened between Sept. 1 and 5 at Williams' 10,000-square-foot home, which is in a well-to-do gated community, Palm Beach Gardens police said in a statement. Police blacked out from their report what was stolen. No arrests have been made.

Palm Beach County property records show Williams and her sister Serena bought the home new in 2000. It is now valued at $2.3 million.

In June, Williams was involved in a traffic accident near her home that killed a passenger in the other car. Police have said the accident investigation remains open, and she is being sued by the dead man's estate. 

Williams, 37, has had one of her best recent years on the court, finishing second at both Wimbledon and the Australian Open and reaching the semi-finals at the U.S. Open.

Williams has seven career Grand Slam titles and career on-court earnings of nearly $40 million.
