Former New York Mayor Rudolph Giuliani is in Peru accompanying presidential candidate Keiko Fujimori on a campaign swing.
The candidate told reporters in the northern city of Trujillo that she invited Giuliani to advise her on citizen security.
Giuliani's role was not clear and his office did not immediately return a call seeking comment.
Fujimori spokesman Alex Toledo told The Associated Press Giuliani would only be in Peru for a few days.
The former New York mayor gained a reputation as a crime-fighter as a U.S. prosecutor in the 1980s.
Fujimori's father, ex-Peruvian President Alberto Fujimori, is serving a 25-year sentence for authorizing death squad killings and corruption.
She meets leftist Ollanta Humala in a June 5 runoff.
