The Shocking Pepper Spray Assault on Guangzhou Metro Line 3
On the evening of April 30, 2026, during one of Guangzhou's typical rush-hour crushes, a seemingly ordinary commute turned into a nightmare for dozens of passengers aboard a Guangzhou Metro Line 3 train. As the train hurtled toward Tiyu Xilu Station, a man dressed in black clothing and wearing glasses suddenly unleashed a canister of pepper spray, spraying it indiscriminately throughout the overcrowded carriage. The acrid fumes filled the confined space almost instantly, triggering waves of coughing, tearing eyes, choking, and sheer panic among riders packed shoulder-to-shoulder.
Video footage captured the chaos: passengers clutching their throats, some doubling over in distress, others desperately trying to shield their faces as they pushed toward the doors. Screams echoed through the carriage, with bystanders yelling for police and urging everyone to stay calm amid the suffocating haze. The incident unfolded in mere seconds but left a lasting scar on those aboard, highlighting vulnerabilities in one of China's busiest urban transit systems.
Timeline of the Terrifying Incident
The attack occurred around 7 p.m., right in the heart of Guangzhou's evening peak, when Line 3—infamously dubbed the 'death line' for its extreme overcrowding—sees load factors exceeding 150 percent. Eyewitness videos shared across social platforms show the suspect standing amid the throng before pulling out the spray. He directed bursts toward fellow commuters without apparent target, affecting men, women, and children alike.
The train doors opened at Tiyu Xilu Station moments later, unleashing a stampede of gasping passengers onto the platform. Several individuals collapsed outside the carriage, rinsing their eyes and faces with whatever water they had. Amid the disorder, enraged riders turned on the perpetrator, surrounding him, punching, and kicking until he lay on the ground, protecting his head. Metro security and police arrived swiftly, detaining the man on the spot.
Eyewitness Testimonies: Voices from the Carriage
Ms. Zhang, a visitor to Guangzhou, recounted her harrowing experience to media outlets. 'My husband suddenly said, "Run!" I smelled a strong, pungent odor right away. Everyone was crying, eyes burning, and the crowd pushed me out,' she said. Another passenger described the scene as 'hellish,' with visibility dropping to zero and throats closing up from the irritant.
Social media exploded with firsthand accounts. One rider posted, 'I thought it was tear gas at first—pure terror in that tiny space.' Videos showed mothers shielding children, office workers vomiting on the platform, and a collective sense of betrayal in a system relied upon daily by millions.
The Suspect: Background and Possible Motives
Described as a young man in his 20s or 30s, the suspect's face circulated widely online after passengers shared clear photos. Speculation swirled around his motives: some claimed he had been caught secretly filming female passengers—a common harassment issue on packed trains—and retaliated when confronted. Others suggested pickpocketing gone wrong.
While unconfirmed, these rumors underscore rising concerns over personal boundary violations in China's megacity transit. The man offered no resistance post-spray but was subdued violently by the crowd, leading to discussions on vigilantism versus justice.
Passenger Heroism and the Violent Restraint
In the absence of immediate security intervention, ordinary commuters became heroes. Despite their own suffering—stinging eyes, labored breathing—they formed a human cordon around the attacker. Punches and kicks rained down as the train halted, a raw expression of fury from a violated public.
This self-defense turned mob justice raises questions: Was it proportionate? Experts note that in high-stress survival scenarios, such reactions are instinctive, but legal boundaries exist. No charges against the passengers have been reported, with authorities focusing on the primary aggressor.
Health Impacts: From Irritation to Hospital Visits
Pepper spray, or oleoresin capsicum (OC) spray, contains capsaicinoids that inflame mucous membranes, causing temporary blindness, coughing, and skin burning lasting 20-90 minutes. In a sealed metro carriage, effects amplify dramatically.
Dozens sought medical aid; symptoms included vomiting, respiratory distress, and corneal abrasions. No fatalities occurred, but the psychological trauma lingers. Hospitals near Tiyu Xilu treated over 20 victims that night, administering eye washes and oxygen.

Official Reactions: Police Confirmation and Ongoing Probe
Guangzhou Metro police swiftly verified the substance as pepper spray—a controlled item under China's public security regulations. The suspect was criminally detained the same evening, with investigations probing intent, procurement, and security bypass.
As of May 4, no formal police bulletin details charges, but precedents suggest penalties for 'picking quarrels and provoking trouble' or assault, potentially 5-10 years imprisonment. The metro operator issued no public apology yet, focusing internally on incident review.Dim Sum Daily's coverage notes the rapid arrest praised by netizens.
Security Failures: How Did It Pass Checks?
Chinese metros, including Guangzhou's, employ airport-style scanners: X-ray bags, metal detectors, and manual pat-downs. Yet pepper spray—disguised perhaps as perfume—slipped through, sparking outrage over 'illusory security.'
- Daily scans process 10 million riders, straining staff.
- Liquid detectors miss small canisters.
- Line 3's volume overwhelms protocols.
Post-2024 knife attacks, Guangzhou enhanced measures, but this exposes gaps. Netizens demand AI scanners and more patrols.
Pepper Spray Laws and Restrictions in China
Pepper spray falls under Category 84 'explosives and hazardous chemicals,' requiring permits for purchase and carry. Public transport bans it outright, with violations fined up to 500 RMB or detained.
In metros, it's akin to a weapon. This case may prompt tighter vendor controls and resale bans online, where canisters sell cheaply despite regs.World Journal reports highlight the irony: intended self-defense tools weaponized.
Social Media Fury and National Conversation
Weibo's top trend: 'Guangzhou Metro pepper spray man,' amassing millions of views. Comments decried 'social decay' and 'weak security,' with memes mocking the attacker.
Discussions pivoted to urban alienation, harassment spikes, and commuter resilience. Influencers called for 'zero tolerance' zones.
Guangzhou Metro in Context: A Behemoth Under Pressure
Handling 9.5 million daily trips, Guangzhou Metro spans 612 km, Line 3 alone ferrying 2 million riders. Peak overcrowding fosters friction: pickpocketing, groping, shoving.
Stats from 2025: 1,200 metro disturbances nationwide, mostly verbal. Violent acts rare but amplified by density—equivalent to 8 Tokyo trains per run.
