Man held in air traffic controller murder probe

SWISS police yesterday arrested a man, who lost his wife and two children in a mid-air collision, on suspicion of stabbing to death the air traffic controller blamed for the crash.

Zurich prosecutor Pascal Gossner said the 48-year-old man has denied killing 36-year-old Peter Nielsen at his home on Tuesday night.

Gossner and the police said it could have been an "act of revenge". He declined to give the arrested man's nationality, although he said the man had only been in Switzerland since February 18, six days before the murder.
