Beer festival had closed after 57-year-old man shot parents, set house on fire, and left note mentioning event

A German man went on a deadly gun, explosives and arson rampage against his family and then killed himself on Wednesday, prompting security fears in Munich that closed the world-famous Oktoberfest for seven hours.

Authorities decided to close the event temporarily after finding a note the man had dropped in a nearby letterbox that included a vague threat to the Bavarian city’s beer festival.

The mayor of Munich, Dieter Reiter, then gave the all-clear in the afternoon and the event reopened in the evening.

Police said the 57-year-old man had opened fire on his parents with a self-made weapon in an attack that started before dawn. He then set their house on fire, having earlier booby-trapped the building.
