AT least three senators have expressed intention to investigate the recent anti-drug operations by police in Bulacan and in some parts of Metro Manila that led to the killing of 74 people, including a 17-year-old Grade 11 student, this week.

Sen. Paolo Benigno “Bam” Aquino said he was planning to file a resolution next week to look into the death of a certain Kian Lloyd delos Santos, 17, during an anti-illegal drug operation in Caloocan City.
