What exactly does it mean, that plane has diverted due to the needs of a passenger? Twitter account for Flightradar24 has reported twice in past 24 hours about two different British Airways flights that has diverted their original route "due to the needs of a passenger" (here and here).

What exactly does it mean? Is it:


a passenger requesting to land on other airport, because he forgot his wallet?
operational decision to put more passengers on-board empty plane?
something else?
The only passenger needs that would result in a non-scheduled landing would be a medical emergency or acts/threats of violence of the level that prompt removal of the passenger is needed (with law enforcement coordination).

A passenger forgetting his wallet would not result in a diversion.  An aircraft deviation to enplane more passengers and proceeding to the scheduled destination would be a highly unusual situation and would not be for passenger needs, it would be for operational needs.
