FBI conducting probe at Houston school district offices Federal agents have descended on the administrative offices of the Houston Independent School District, although it's unclear what they are investigating

HOUSTON -- Federal agents descended on the administrative offices of the Houston Independent School District on Thursday, although it's unclear what they were looking into at one of the county's largest school systems.

FBI agents arrived at the school offices at around 8 a.m. for what FBI spokeswoman CJ Jones would only describe as a “court-authorized law enforcement activity." She said there is no threat to the public's safety.

Agents from the FBI and IRS carried boxes as they walked out of the building, which is about 7 miles (11 kilometers) northwest of the city's downtown, in the early afternoon.

The district said in an emailed statement that there was no danger to students or staff and that it was "fully cooperating.” District officials didn't immediately reply to requests for comment.

Federal agents were also seen at the suburban home of an HISD administrator Thursday. It's unclear if the two actions are related, and Jones did not immediately respond to questions.
