Imbestigador (English: Investigator) is an investigative show that tackles anomalies and inconsistencies in the Philippine government. It criticizes the corruption in the Philippine society, from overpriced items to arms smuggling, covering a wide variety of topics that sometimes include Filipino traditions and beliefs. It is a public service show that aims to inform the people of the current problems troubling the Philippines. Mike Enriquez hosts the show since he became the anchor of "Saksi" in 1995, with Karen Davila and Mel Tiangco, and "GMA Network News" with his former partner, Vicky Morales, in 1998.
It is originally aired during Wednesdays from 2000-2003 then they moved to Saturdays from 2003 to 2012. On August 5, 2012, Imbestigador is now new timeslot every Sunday at 6:00PM (PHT) after 24 Oras Weekend starting August 5 in observance of the show's 12th year.
The show on January 1, 2012 has "caught-up" on GMA Pinoy TV and is no longer one-week delayed due to the show being pre-empted on December 31, 2011 in lieu of "Trending 2011: The GMA News and Public Affairs Yearend Special" for 2011, which was also hosted by Mike Enriquez with Dingdong Dantes.
