The police chief noted that investigators have collected critical evidence including the condition of the victim’s helmet after it was removed following the caustic attack, the position of the victim’s motorcycle after the attack, and a red-coloured liquid suspected to be a hazardous substance found on a bridge railing.

The Directorate of Criminal Investigation of Metro Jaya Police announced that investigators have obtained footage from 86 surveillance camera locations related to the suspected route taken by the perpetrators.
