Police Explain Why Ruben Onsu Has Not Been Detained in Alleged Fraud Case

Investigators from the South Jakarta Metro Police Criminal Investigation Unit have named Ruben Onsu a suspect in an alleged investment fraud case. Police stressed that detention is the authority of investigators.

“Of course he will be examined first, examined first as a suspect. Later, whether detention is carried out or not will depend on the investigation process,” said South Jakarta Metro Police Public Relations Head AKP Joko Adiwibowo to reporters on Wednesday (26/8/2026).

His office has issued a summons for Ruben Onsu to appear on Friday, 28 August 2026. However, he said there has been no confirmation of attendance from Onsu’s side so far.

“Until now there has been no confirmation of his attendance. Of course we will wait until the time stated in the summons arrives,” he said.

Police are still waiting until the scheduled summons time. If Ruben Onsu disregards the summons, a second summons will be issued.

“We will just wait and see what the summons schedule looks like, whether he comes or not. If he does not respond to the summons, a second summons should be sent,” he said.

The Case Background

Previously, Joko said the report against Ruben was registered under number LP/B/310/VIII/2025/SPKT/Polres Jakarta Selatan, dated 22 August 2025. The complainant in this case has the initials P, while the victim has the initials DM.

In the report, Ruben is alleged to have offered the victim an investment in a business he owned. In short, an agreement was reached between the two parties, with the victim handing over a sum of capital.

“The chronology is that the reported party has a business, then offered the victim the opportunity to invest funds. The victim was then interested in carrying out the agreement between the victim and the reported party,” Joko told reporters on Thursday (20/8).

“An agreement was then drawn up with the victim handing over a sum of capital, along with an agreement on the promised profits,” he added.

In the report, Ruben Onsu is alleged to have failed to provide the profits and return the capital that the victim had deposited. As a result, Ruben was reported to the South Jakarta Metro Police.

“When the agreed time arrived, the profits had not been received and the capital had also not been returned. In relation to that, the victim reported this incident to the South Jakarta Police,” he said.
