The provided article text does not contain the actual story content — only the headline and a list of unrelated Daily Mail sidebar headlines were supplied, with the genuine article body missing or cut off. As a result, no verified details are available about the British sprinter, their identity, or the circumstances of their disappearance in Morocco.

Without the full article text, it would not be possible to accurately or neutrally summarise what happened, when the trip took place, or what authorities have said. Please provide the complete article text so a proper summary can be produced.
