Late June this year, somewhere in central Europe:
Up to 20 students have collapsed partly unconscious during the graduation ceremony at the regional police academy. A thorough investigation followed to explore all possible angles also to rule out unlawful interference and biological attack, to much relief no physiological reason was found. Among possibilities specifically tested was drug (legal and illegal) abuse, alcohol intake, sleep deprivation, and intoxication from external contaminants.
The final conclusion on the most likely chain of events is faints of a single girl student, followed by her two female friends standing near, possibly from hyperventilation. This may have triggered a cascade crowd reaction, compounded by the stress of the occasion and possibly boy students wearing ties and formal suits on a hot day for the first time.
