FBI agents removed boxes from a Detroit-area home during an evening search.

Agency spokesman Tim Wiley described the search late Thursday in Dearborn as a "law enforcement operation" but said there's no threat to public safety.

The Detroit Free Press and other local media outlets, citing a source they do not identify, reported the search was related to a "national security" issue. The Free Press , which cited "a source familiar with the mission," reported it involved an incident that "apparently happened out of state."

The newspaper later reported the security issue was not about a planned terror attack.

Wiley told The Associated Press that he won't comment on those reports. WXYZ-TV video showed agents removing boxes Thursday night. The Detroit News said agents left the scene shortly before midnight.
