The Policía de Investigaciones del Perú or Peruvian Investigative Police (PIP) was a Peruvian plainclothes police unit, similar to the United States Federal Bureau of Investigation (FBI), which was meant to investigate crimes, gather intelligence, and fight subversion. In 1988, the PIP was merged into the National Police of Peru, along with two other police forces, the Guardia Civil (GC) and the Guardia Republicana (GR), all three of which were under the direction of the Ministry of Interior.
