MARTIGNY, Switzerland (AP) — Switzerland held a national day of mourning on Friday for the 40 people who died in an Alpine bar fire during a New Year’s Eve celebration, as prosecutors requested one of the managers to be placed in pre-trial detention.

Valais region’s chief prosecutor Beatrice Pilloud said in a statement the detention of the man was needed to avoid a “risk of flight.” The man's wife and co-manager will remain free under judicial supervision, the statement said.
