It can be recalled that in July last year, Dela Rosa was one of the Philippine National Police officials who were tagged as “suspects” for the alleged crimes committed during the Duterte administration's anti-narcotics campaign. Veronica Duterte, also known as “Kitty,” filed a habeas corpus petition for his father on March 12.

The Philippine Senate said Monday it will conduct a formal probe of ex-president Rodrigo Duterte's arrest and swift handover last week to the International Criminal Court, which is to try him for alleged crimes against humanity.
