During the search, members of the Densus found a warehouse of chemical liquids that would be used as explosive materials. "After the arrest was made, the search continued, and we found in the storage place several chemical liquids that have indeed been used in several previous cases as materials for making bombs or explosive materials," he said.

The actor purchased explosives raw materials to be sent to his home. This was also known by the actor's parents. Not only that, the actor's parents apparently also knew about the manufacturing process and the actions of HOK. "According to his confession, which we are currently investigating, the ordering, then the manufacturing, the order was made using the address at home, then also the manufacturing at home, and this was known by the parents or the family concerned," said Aswin.

The perpetrator, who is still a student, purchased explosives using savings from their allowance received from their parents. "The cost or funds used for the purchase of these materials were obtained by the individual through their own savings. The allowance, according to their statement, was given by the individual's parents," revealed Aswin.

"Of course, we are here to urge that as parents or as part of the family members who know about such things, to immediately stop or we are very open to receiving reports if there are things that are emergency in nature, we say it like this," he said.
