CHARLOTTE, N.C., - FBI agents searched the North Carolina house of Paula Broadwell on Monday, signaling renewed activity in the investigation that revealed her extramarital affair with CIA Director David Petraeus that led to his resignation.

Agents entered the house in Charlotte, North Carolina, carrying boxes around 9:00 p.m. (0200 GMT Tuesday) and were still there almost two hours later.

US officials had said in recent days that their investigation in the Petraeus affair was largely complete and that prosecutors had determined it was unlikely they would bring charges in the case, which started as suspected cyber-harassment involving Broadwell and Jill Kelley, a Petraeus friend.
