Ye Lin didn’t just send a joke to a colleague. He triggered a full-scale manhunt. On August 20, at 3pm, Singapore’s national water agency, PUB, got a tip: a crocodile was spotted at Pandan Reservoir. Attached was a photo. It looked real. PUB didn’t hesitate. They called the National Parks Board (NParks). Boats launched. Drones flew. Search teams combed the shoreline. It was a genuine public-safety operation, and it cost the city two full days of suspended water activities. The Singapore Rowing Association and Canoe Federation had to pull their plugs.
The twist? The crocodile was code. PUB eventually ran the image through AI-detection tools, but the results were murky. The software couldn’t definitively prove it was fake, so officials played it safe. They assumed the threat was real. That precautionary stance ended only when PUB confirmed the image was synthetic and filed a police report. The man who sent it? Ye Lin, 30, a Myanmar national. He worked for a reservoir-maintenance contractor. His own supervisor—the very person who reported the sighting to PUB—was the one who tipped off authorities to the source.
The damage was already done. Police allege Ye didn’t just share the image; he tried to bury it. Investigators found he deleted the AI-generated files and the log history from the Gemini AI app on his phone. That act of digital cleanup added a second hammer to his head: obstructing the course of justice. He appeared at Singapore’s State Courts on September 29. Through an interpreter, without a lawyer, he said he would plead guilty.
The stakes are high. Under Section 14D of the Miscellaneous Offences Act, the false message charge carries up to three years in jail and a S$10,000 fine. The obstruction charge under the Penal Code adds another seven years. Ten years max, stacked. But the court will decide the final tally. His case returns on November 10, where the judge will weigh the severity of his prank against the disruption it caused. For now, the reservoir is open, but the warning is loud: don’t feed the algorithm a lie and expect the authorities to shrug.
