Police Also Arrest Drug Dealer Ko Erwin's Treasurer in Mataram
JAKARTA — The Indonesian National Police Criminal Investigation Directorate (Bareskrim Polri) has arrested a fugitive wanted in a narcotics case named Ais, who is believed to be the treasurer of major drug dealer Erwin bin Iskandar, alias Ko Erwin (57).
The arrest of Ais was carried out in Mataram, West Nusa Tenggara (NTB), on Thursday, 26 February 2026.
At virtually the same time, Bareskrim arrested Erwin in North Sumatran waters near Malaysia.
“Ko Erwin also has associates, and one of his wanted fugitives has been arrested under the name Ais, who served as treasurer. We arrested him in Mataram,” said Kombes Roman Smaradhana, Director of the NTB Police Narcotics Investigation Unit, whilst providing a statement at Bareskrim Polri on Friday, 27 February 2026.
From the arrest, investigators were only able to seize one mobile phone as evidence.
Investigators are currently searching for bank accounts used by Ais to collect proceeds from drug sales within Erwin’s network.
Ais and other suspects will be brought to Bareskrim Polri for further questioning.
Erwin was arrested in North Sumatran waters aboard a vessel that was attempting to transport him illegally into Malaysian territory. The arrest took place on Thursday, 26 February 2026, and Erwin was brought to Bareskrim Polri on Friday, 27 February 2026.
According to police records, Erwin is an Indonesian national born in Makassar on 30 May 1969. He is known to have several addresses in West Nusa Tenggara (NTB) and South Sulawesi (Sulsel).
Erwin is suspected of acting as a drug dealer in Kota Bima, NTB, and is alleged to have deposited 2.8 billion rupiah with the former Kota Bima Police Chief, AKBP Didik Putra Kuncoro.
Didik’s involvement in this matter came to light after the NTB Police uncovered the involvement of a police officer in the drug trafficking network in Kota Bima, specifically Maulangi, who previously served as the Head of the Narcotics Unit at Kota Bima Police Station.
From questioning Maulangi, police discovered a flow of funds received during the period from June to November 2025.
“The total amount of money handed over to AKBP DPK amounts to 2.8 billion rupiah,” stated Eko.
Since 16 February 2026, the NTB Police have named Didik as a suspect for allegedly receiving proceeds from illegal drug trafficking.
In addition to the funds case, Didik is also facing charges related to drug possession, which is now being handled by Bareskrim Polri.
