The death toll from violent unrest at Negombo Prison in Sri Lanka has reached 25, with more than 100 injured, according to officials from the Prisons Department. The escalation occurred on July 6, 2026, when inmates seized prison firearms during clashes that began the previous day between rival groups allegedly linked to drug trafficking operations.
Police Special Task Force (STF) units and riot control teams deployed to the facility opened fire to restore order. Among the dead are four prison officials and guards, while the majority of the injured are security and correctional personnel. Three inmates have been transferred to Pallansena Prison Camp as authorities work to stabilize the situation.
Latest situation update
Sri Lanka's Minister of Justice has called for a detailed report on the incident, while both the Prisons Department and police have launched separate investigations. A magisterial inquiry has been conducted to determine the sequence of events and accountability. Preliminary findings from officials indicate the violence stemmed from clashes between inmate factions supporting and opposing drug trafficking activities within the prison.
The seizure of firearms by rioting inmates represents a significant breach of institutional security. The incident highlights longstanding concerns about overcrowding in Sri Lankan prisons, which currently hold approximately 41,250 inmates as of July 5—roughly four times their designed capacity. This overcrowding mirrors security challenges seen in other regional contexts where institutional strain creates vulnerabilities, including recent coordinated assaults on Pakistani security facilities where insurgents exploited gaps in perimeter control.

Investigations underway
The parallel investigations by the Prisons Department and police will determine whether the unrest resulted from inadequate security measures, staff complicity, or the influence of external criminal networks operating through incarcerated members. Sri Lankan prisons have experienced periodic unrest related to overcrowding and conditions, but the seizure of institutional firearms and the resulting casualty toll distinguish this incident from previous protests or disturbances. The outcomes of these inquiries will shape both immediate security protocols and longer-term reforms to address the structural overcrowding that creates environments where such violence can escalate rapidly.
