MOYOCK, N.C. (AP) Authorities in northeastern North Carolina say a helicopter has crashed on the campus of private security contractor Xe (zee).

Currituck County Sheriff Susan Johnson said the crash occurred near the company's administrative building Tuesday afternoon. She did not know any other details about the incident.

Xe is the security and training company formerly known as Blackwater Worldwide. A company spokeswoman did not immediately return calls seeking comment.

Xe's campus is in Moyock, a tiny community about 30 minutes south of Norfolk, Va.
