CHARLOTTE, N.C. (AP) — FBI agents on Monday night searched the North Carolina home of the woman whose affair with retired Gen. David Petraeus led to his resignation as CIA director.

FBI spokeswoman Shelley Lynch said agents went to Paula Broadwell's home in Charlotte, but declined to say what they were doing there.

The agents appeared at Broadwell's home carrying the kinds of cardboard boxes often used for evidence gathering during a search. They walked through the open garage of Broadwell's house and knocked at a side door before entering the home. One person was taking photographs of the house and its garage as members of the news media watched.

Petraeus resigned his CIA post last week after acknowledging an extramarital affair.
