On October 4, 2017, at 16:45, the Hungarian Cave Rescue Service received an alert that a young man had suffered a knee injury in the Mátyás-hegyi cave (part of the Pál-völgyi cave system) in Budapest - the same cave where an accident had also occurred five days ago.
We immediately issued the alarm and then began marching to the scene with medical and rescue equipment.
The site of the accident is one of the very narrow passages of the cave, the so-called "Sandwich" squeeze.
Here, a member of a hiking group, David S. (a 22-year-old American citizen) sprained his knee while he crawled on all fours through the narrowest section. His injury was very painful, so he was unable to continue the tour.
