The man who shot and injured three people in a Muslim prayer hall in Zurich was a 24-year-old Swiss national interested in the occult who committed suicide after the attack, Swiss police said Tuesday. 

The gunman, whose body was found near the scene of the crime, was also implicated in a murder at a playground in the city on Sunday, head of Zurich cantonal police Christiane Lentjes Meili told reporters, adding: "We don't know anything about the motives."
