JAKARTA – Police in Indonesia’s Surabaya have detained foreign nationals, including Japanese, for suspected involvement in fraud, according to Indonesian media reports.

The Surabaya authorities announced the development Friday, while the Japanese Consulate-General in the East Java city was informed on April 22 about the detentions of six Japanese nationals.

The authorities seized clothing resembling police uniforms and other items believed to have been used in the fraud. They believe that the detained people contacted individuals in Japan, posing as police officers.

The investigation began following a report from the Japanese Consulate-General that there was suspicion that two Japanese nationals had been kidnapped.

In a video posted by Indonesian police on social media, a woman said in Japanese, “I was forced to come here, my passport was taken away, and I was told, ‘You can’t go home anymore.'”

In March, immigration authorities in Indonesia detained 13 Japanese nationals related to fraud near Jakarta.
