FBI agents opened an antique safe concealed behind a wooden panel in a former San Francisco office building. The safe, which dates back over a century, contained nothing but scribbled Post-It notes.

Why it matters

The investigation was initiated after Kink.com, the current building owner, alerted federal authorities to the safe following inquiries from local reporters. It adds a peculiar chapter to the history of the property formerly linked to a high-profile corruption case.

A certified master safe-cracker successfully breached the safe in 15 minutes using a carbide-tipped drill and internal scoping tools. This action followed a formal report by current owners to the FBI.

While the property was previously owned by Walter Wong, who pleaded guilty to federal charges in 2020 involving $1.5 million siphoned from the Chinatown Hilton, agents also toured a secret floor within the structure.
