The attack at Ratchaprasong
On the evening of August 17, 2015, an explosion struck the Erawan Shrine near Bangkok's busy Ratchaprasong intersection. Twenty people were killed. Fourteen of the dead were foreign nationals and six were Thai, according to reporting on the 2026 judgment.
Reliable sources are not perfectly uniform on the injury count. Reuters reported 120 injured in its June 2026 account of the verdict, while Thai PBS reported 160. Crime by Region therefore uses more than 100 injured rather than presenting a disputed number as exact.
Investigation and arrests
The investigation quickly expanded across Bangkok and beyond. Adem Karadag, also known in court records as Bilal Mohammed, and Yusufu Mieraili were arrested in the weeks after the bombing and later prosecuted. Other people were named or sought during the broader investigation, but this page does not treat someone as convicted merely because an arrest warrant, allegation or investigative theory existed.
Authorities put forward different explanations for the motive over time. No organization publicly claimed the bombing. International reporting has discussed possible retaliation connected to Thailand's treatment of Uyghurs, while other theories also circulated. Because motive was not established through a separate final adjudication broad enough to resolve those competing explanations, this page does not present any one theory as proven fact.
A trial that lasted more than a decade
The prosecution began in the military-court system and was later transferred to a civilian court after policy changes returned civilian cases to ordinary jurisdiction. Witness examination had to restart. Proceedings were then slowed by interpreter difficulties, the number of witnesses and evidence, and disruption during the Covid-19 period.
By June 2026, the case had stretched into its eleventh year. Nation Thailand reported more than 400 prosecution witnesses, more than 45 defence witnesses and tens of thousands of pages of court material. The delay is a material part of the case history because the eventual verdict arrived nearly eleven years after the bombing.
The June 2026 judgment
On June 11, 2026, the South Bangkok Criminal Court convicted Adem Karadag and Yusufu Mieraili on charges that included premeditated murder and sentenced both men to death. Thai PBS and Nation Thailand reported that the court found no grounds to mitigate the punishment.
The defendants continued to deny responsibility. Reuters reported that both planned to appeal, and Karadag's lawyer publicly said the defence would challenge the verdict. That distinction matters: a first-instance conviction is a judicial finding, but it is not the same as a fully exhausted appellate process.
Due-process allegations
The defence raised objections over identification evidence, interpretation and treatment in custody. These are allegations and legal arguments, not findings that automatically invalidate the judgment. Conversely, reporting a conviction does not require erasing the existence of disputed procedural issues. The appropriate editorial treatment is to state both the court's conclusion and the defence's continuing challenge accurately.

Current status
As of the latest reliable material reviewed for this file, the case is partially adjudicated with appeals pending. Two defendants have been convicted and sentenced to death at trial, but they deny guilt and announced appeals. Crime by Region did not locate a later appellate judgment that replaced or finalized the June 11, 2026 ruling.
The page therefore does not describe the convictions as fully final and does not state a proven organizational motive beyond what the court judgment established against the two defendants.
