A student spoofed the rail network's emergency radio signals, halting multiple Taiwan bullet trains

Taiwan police say a 23-year-old student used radio gear to mimic emergency rail signals.

The spoofed signal triggered a 48-minute stoppage that disrupted multiple Taiwan High Speed Rail trains.

Investigators seized devices, arrested a suspected accomplice, and are widening the probe.

The case has raised fresh concerns about communications security in critical transport systems.
