Periscope used by French teenager to live-stream her own suicide

Prosecutors launch inquiry after 19-year-old uses Twitter's service to film herself jumping in front of train in Paris

French prosecutors have launched an investigation after a 19-year-old woman killed herself by jumping in front of a suburban train in Paris and streamed the act live on Periscope.

The unnamed French woman "sent a text to one of her friends several minutes before her death to make them aware of her intentions", said the prosecutor Eric Lallement on Wednesday.
