A security-related incident paralyzes Paris Metro Line 9

Field sources and consistent reports indicate that power to the entire line was urgently cut off for safety reasons. This caused ventilation systems inside the train cars to shut down, leaving hundreds of passengers trapped underground in difficult conditions—marked by a lack of oxygen and a sudden rise in temperature within the overcrowded carriages.

A Controversial Message via the Public Address System

In a notable development—documented by passengers and journalists on the scene, including French journalist Gaspard Glanz—the injured driver addressed the passengers over the train’s public address system to explain the reason for the sudden stop. According to circulating recordings and the news account "AlertesInfos," the employee concluded his message by invoking the slogan "ACAB" (an anti-police acronym). This action sparked widespread reaction and intense debate on social media, with some condemning the sentiment, while others expressed surprise at the driver’s response.

A Charged Security Context

This incident coincides with violent confrontations taking place today on the streets of Paris between French security forces and groups of protesters. Several neighborhoods have seen running clashes and the heavy use of tear gas by police to contain the demonstrations, suggesting that the incident may be linked to the broader security tensions surrounding the city’s transport network.

As of the time of this report, the Paris Autonomous Transport Authority (RATP) has not issued an official statement regarding the driver’s medical condition, the measures taken to evacuate the stranded passengers, or the status of efforts to resume service on the line.
