Control of Drug Circulation from Prison: Robig Zaenudin, Killer of Gamma Rizky, Transferred to Nusakambangan
Convicted in the shooting case of SMKN 4 Semarang student Gamma Rizkynata Oktafandy, Robig Zaenudin has been moved from Semarang Class I Prison to Nusakambangan Prison. The transfer was carried out because Robig is suspected of controlling drug circulation from within the prison.
Head of Semarang Class I Prison Ahmad Tohari confirmed that Robig’s relocation to Nusakambangan Prison was prompted by a drug control case. “Semarang Class I Prison received several complaints from the public regarding allegations of drug control outside the prison by one of the inmates named Robig Zaenudin,” Tohari stated in his comments obtained by Republika on Thursday (23/4/2026).
He added that a few days later, the Central Java Police Narcotics Directorate conducted an examination of Robig. “Therefore, as a precautionary measure against this issue, Semarang Class I Prison took swift action to transfer the inmate to Class IIa Gladakan Nusakambangan Prison to prevent potential disruptions to security and order,” Tohari said.
Tohari revealed that 40 inmates, including Robig, were transferred from Semarang Class I Prison to Nusakambangan Prison. The transfer was carried out on 4 February 2026. Twenty inmates were sent to Class IIa Gladakan Nusakambangan Prison, while the rest went to Class IIb Nirbaya Nusakambangan Prison.
The transfer of the inmates was based on the Letter from the Head of the Central Java Directorate General of Corrections Regional Office Number: WP.13-PK.03.02-29 dated 30 January 2026. According to Tohari, the transfer of these 40 inmates is aimed at improving the effectiveness of guidance, social reintegration, and early detection of security and order disruptions.
“In accordance with Article 45 paragraph 1 of Law Number 22 of 2022 on the Correctional System, the transfer of prisoners is carried out considering several factors, namely guidance needs, preventing potential security and order disruptions, and addressing overcapacity,” Tohari stated.
