Inspector Elmer Monsalve, chief of the homicide investigation section of the Quezon City Police District (QCPD), said "Arnie" (not his real name) was questioned over the death of 14-year-old David hours after the two of them figured in a fight.
Investigators learned from witnesses that Arnie was being picked on by the older boy until he got fed up and struck back by delivering a strong blow on David's back.
Later that afternoon, David started vomiting at home prompting his parents to take him to the Bernardino General Hospital. It was there where David died.
In the evening, barangay public safety officers (BPSOs) took Arnie to police stationed at Camp Karingal to give his statement to probers.
On Monday, it was learned that Arnie had been turned over to the Department of Social Welfare and Development (DSWD) on account of his being a minor.
