WASHINGTON, Dec. 3 - Officials at the Federal Bureau of Investigation mishandled a Florida terror investigation, falsified documents in the case in an effort to cover repeated missteps and retaliated against an agent who first complained about the problems, Justice Department investigators have concluded.

In one instance, someone altered dates on three F.B.I. forms using correction fluid to conceal an apparent violation of federal wiretap law, according to a draft report of an investigation by the Justice Department inspector general's office obtained by The New York Times. But investigators were unable to determine who altered the documents.
