MANILA, Philippines ? The National Bureau of Investigation (NBI) filed on Monday criminal cases against two brothers who supposedly uploaded into the Internet the sex videos of cosmetic surgeon Hayden Kho's intimate trysts with actress Katrina Halili and two other women.

Palmer Mallari, executive officer of the NBI Anti-Fraud and Computer Crimes Division, said Joebert and Marvin Lazarte were charged with violation of Article 201 of the Revised Penal Code before the Cavite provincial prosecutor's office.

Mallari said their investigation showed that the brothers were the "maintainers" of the website www.fleshasiadaily.com where the sex videos featuring Kho and at least three women were first uploaded.

The Lazartes were arrested along with their father, Fidel, during a raid on their house in Bacoor, Cavite, on Friday.

Mallari said they released the suspects' father after they were able to confirm that he did not have any knowledge of his sons' activities.

Mallari said they learned in their investigation that an anonymous person sent the Lazartes copies of the videos by email. The NBI is now trying to trace the ownership of the sender?s email address.
