Shot for Requesting Dengue Medicine? Unpacking the Claims Behind the Negombo Prison Deaths

Subscribe to our WhatsApp Channel

Negombo Prison erupted into the deadliest bout of prison violence Sri Lanka has seen in years in early July 2026, with 20 inmates and 7 officials killed inside 24 hours and relatives massing outside the gates for news. In the middle of that chaos, a post-style to look like an Ada Derana news card spread fast, claiming that inmates who had caught dengue and asked for medicine were shot dead by guards. We investigated. Here is what we found.

Fact Check

We ran down the photograph and headline circulating on social media and confirmed both are genuine, drawn from a real news report on the clash among inmates at Negombo Prison on July 5, 2026. The image and headline do relate to the Negombo Prison clash. The problem lies in what was added to them.

A Fabricated Caption Was Added to a Genuine Ada Derana News Card

The viral post uses the real news-card template from Ada Derana’s Facebook page. But when we checked the original post, we found that a fabricated line claiming inmates were shot for asking for dengue medicine had been added on top of it, as shown below.

The Clash Was a Drug-Trafficking Feud, Not a Dengue Dispute

Our investigation found that mainstream outlets traced the clash to retaliation over a drug-trafficking operation run inside the prison. Those reports can be read here, here and here.

On the afternoon of July 5, 2026, a clash broke out at Negombo Prison between two groups of inmates who act as associates of two drug traffickers now based in Dubai. Preliminary inquiries indicate it was triggered after another party tipped off prison officials about a group running a drug operation inside the facility.

The headline in the social media post, “Five dead, including three prison officers,” refers to this very stage of the incident.

To regain control, additional police and prison units, including the Police Special Task Force (STF), were sent into the facility. Reports say inmates attacked with iron rods, stones and sharp weapons, and security personnel had to fire several shots to contain the unrest.

Across both days, media reports said the toll climbed to 25 within roughly 24 hours, with more than 100 injured. The Commissioner General of Prisons appointed a special committee to investigate.

As of July 7, the toll had risen further to 27, made up of 20 inmates and seven prison officers, with 77 people in hospital and three separate government investigations under way, according to reporting carried by AP. Officials said the inmates who led the violence were transferred to other prisons once order was restored. None of these changes the core finding: the deaths came from the prison feud, not from anyone being shot for asking for dengue medicine.

There Is No Link Between Dengue and the Prison Clash

None of the media reports or the statements from prison officials and police that we examined tie this clash to people seeking dengue treatment. Dengue cases have indeed risen across the country in recent days, but that is a wholly separate matter. As set out above, the Negombo Prison clash grew out of a drug-trafficking feud among inmates.

There is a reason the dengue angle surfaced. During the unrest, inmates climbed onto the prison roofs in protest and, at that moment, were reported claiming that people inside were dying of dengue and being denied medicine, as seen in this footage. But because the clash took place in a men’s prison and began as a drug-trade feud, the relevant authorities confirm it was not a clash caused by dengue infection or a request for medicine.

Police Media Division

We contacted the Police Media Division for clarification. They confirmed that the clash was not related to dengue and arose instead from retaliation linked to a drug-trafficking operation.

Conclusion

Our investigation confirms that the social media post is false. It took a genuine photograph of the Negombo Prison inmate clash and a real Ada Derana news card, then falsely reframed them to claim inmates were shot dead for asking for dengue medicine.

The real event was a clash between two rival drug-trafficking groups inside the prison, which escalated into further violence between inmates and prison officers and left many dead and injured. The claim that people were shot for requesting dengue medicine does not hold up.
