The arrest of dive instructor William Armstrong follows months of scrutiny after the young student died during a certification course in August 2025. As previously reported by X-Ray Magazine, the case raised serious questions about supervision, training standards and the handling of evidence in the aftermath of the accident. At the time, concerns were also voiced about missing dive computer data and the apparent lack of a thorough initial investigation.

Acuthorities said the instructor was taken into custody this week on charges related to the incident. Details of the charges and the legal process ahead have not yet been fully disclosed, and investigators have indicated that the case remains ongoing.

Pressure for accountability

The arrest comes amid sustained public and professional pressure for accountability, following the release of disturbing statements captured on video and widely circulated last year. Those remarks, attributed to a dive industry professional, intensified outrage and fuelled calls for stronger oversight of youth training programmes.

While this development does not in itself resolve the many unanswered questions surrounding the case, it represents a significant step forward in what has been a deeply troubling episode for the diving world.

We will continue to follow the case as further information becomes available and report on any additional developments.
