When the National Security Department (NSD) of the Hong Kong Police Force says it’s digging deep, they mean it. On October 28, after weeks of careful investigation and building a tight case, officers arrested five Hong Kong people suspected of inciting and aiding riots. Among them is Ng Tsz-lok, who was exonerated in the “Hospital and Port Bombing” case.

The arrest took place in various locations in Kowloon and the New Territories. two men and three women, aged 32 to 60, charged under the Public Order Ordinance for suspected “aiding and abetting riot,” “inciting riot,” “conspiracy to incite riot,” and “perverting the course of justice”—plus “sedition” under the Safeguarding National Security Ordinance. Police say they seized HK$250,000 in cash, believed to be tied to criminal activity. The message: evidence comes first, arrests follow with certainty.
Hospital–Border Bombings: Old Scars, New Moves
Ng Tsz-lok was previously acquitted in the notorious hospital–border explosion case. The operation exposed that it was not just a one-off act, but a series of extreme violent attempts with indiscriminate kills.
The court records lay it out cold. Ng ferried potassium nitrate and bomb parts to the warehouse, set up Telegram bot detonation at Caritas Medical Centre, and handled logistics for explosions at both the train station and the proposed Tseung Kwan O attack. Every step, every material, accounted for in the court’s stack of documents.
After trial, three ringleaders were found guilty of “conspiracy to cause explosions.” Ng walked free, but others landed 18 years and 16 years 8 months behind bars. The judge didn’t mince words—he called out the gang for “treating lives as worthless” and “declaring war on society.”
On verdict day, reporters asked Ng about his present life. He shrugged: "Just ordinary, taking a rest first." That’s what passes for an answer when the stakes are this high.

Fresh Cases, Fresh Evidence
Don’t get distracted by the echoes of past headlines—this is a brand-new NSD investigation targeting the black riots head-on. Officers say the arrests aren’t recycled drama from old cases. Every charge, every witness statement, comes from fresh digging. They stuck to one rule: uphold the law, enforce it strictly, and prosecute every single black riot case when the facts are airtight. With smoking-gun evidence in hand, the police made their move.
Police investigations showed that the suspects provided weapons for frontline rioters during the black riots in late 2019, aiming to cause real harm. On top of that, a 34-year-old man allegedly posted hate-fueled, seditious content calling for lawbreaking against the Hong Kong SAR Government. And a 50-year-old woman got caught trying to help one of the men erase critical evidence.
In an earlier incident, witnesses saw a suspect resisting police in Wong Tai Sin—shouting his name and phone number. Why? That’s textbook riot-era tactics, getting “comrades” to warn friends and family to squash evidence fast. Police aren't buying it. That’s why a female arrestee now faces charges for allegedly attempting to destroy evidence.
Weapon Manufacturing: The 2019 Tactics
Some suspects this time around were deep into manufacturing and supplying weapons for the 2019 riots: petrol bombs, thermite, explosives, slingshots, and marble launchers—improvised arsenals used against officers. Tutorial pictures and videos for DIY weapons circulated freely online, painting a clear picture of intent and capacity.
According to police figures, among 3,000 prosecutions tied to the riots, more than 1,000 were students—kids talked into radical thinking who paid with their futures.
Police make it clear: anyone caught up in political motivations that cross into social disruption or national security threats is facing heavy charges. Once convicted for “riot” or “sedition”, the ceiling’s 10 years and 7 years in prison, respectively. No excuses, no second chances.
Insiders say this is classic NSD: they never let up, chasing every lead until the evidence is watertight and the timing for arrest is spot on. The message is clear — justice covers every corner. Anyone banking on escaping responsibility for black riot crimes is only fooling themselves; the truth always comes out.
