At least 25 people died following violent clashes between rival inmate groups at Negombo Prison on July 5 and 6, 2024 [1].
The scale of the violence underscores the volatility within the Sri Lankan correctional system and the challenges officials face in maintaining order among competing factions.
The riots broke out at the facility located on the outskirts of Colombo [2]. According to reports, the violence stemmed from a confrontation between two rival groups of inmates [1]. The fighting escalated rapidly, leading to a high casualty count and widespread chaos within the prison walls.
Official reports said that at least 25 people were killed during the two-day period of unrest [1]. While some initial reports suggested the death toll was at least 23 [2], higher-trust sources said the number reached 25 [1]. In addition to the fatalities, more than 100 people were injured [1].
Prison officials and security forces intervened to suppress the riots and restore control to the facility [2]. The specific nature of the weapons used or the exact catalyst for the initial confrontation between the rival groups has not been detailed in the available reports.
Negombo Prison serves as a critical holding facility for the region, but the severity of this incident highlights the risks of inmate gang dynamics. The casualties include both inmates and potentially other staff involved in the response, though the primary conflict centered on the rival prisoner groups [1].

The deadly riots at Negombo Prison reflect a systemic failure in inmate segregation and conflict resolution. When rival factions are housed together without adequate oversight, small disputes can escalate into mass-casualty events, necessitating a review of security protocols and the psychological management of prisoners in the Colombo region.
