Police were left empty when they raided a hotel room in Kuta, suspected to be the operational center of an online gambling network on Saturday.
The raid took place at 8 p.m. on Saturday at a hotel on Kartika Plaza Road.
Denpasar Police Chief Bambang Yugo Pamungkas, who led the raid, said the perpetrators fled and officers instead found abandoned devices in the room, including four computers, seven Wi-Fi routers and four smartphones, as well as SIM cards.
It is presumed that plans for the raid had leaked, giving the perpetrators time to escape from the Kuta Hotel.
“From the evidence we have collected, this hotel room was used as an online gambling site,” Bambang explained.
“The attacker booked the room for some time, raising suspicions who were later alerted [the police]added Bambang.
Police are questioning hotel management and staff as they search for more leads to capture the gambling ring. The devices found in the deserted room were confiscated as evidence.
Gambling is illegal in Indonesia.
In June, Bali police arrested an Australian national and his two Indonesian assistants for arranging a horse bet in a Seminyak pub.
