That's according to the BBC, which said the official was a 74-year-old man who died after being rushed to the hospital Sunday:
The official, named locally as Dieter Strack, had gone to measure a throw but was hit by a javelin before it hit the ground, according to local media.
The competition was called off after the incident.
The 15-year-old competitor who threw the javelin is receiving psychological counselling, police spokesman Andre Hartwig told the Associated Press.
Police are investigating, but the incident appears to have been an accident. Which, from time to time, can happen.
