French police say they've detained 22 people across France in an investigation of a suspected computer hacking network.
The sweep stems from a probe begun in the eastern city of Dijon in February after about 30 domestic and foreign companies reported cases of computer network vandalism and destruction of some files.
Police say the motives are not immediately clear. They are not ruling out economic espionage.
Authorities say the suspects in the network appeared to challenge one another in online forums. Most are young _ with one aged 13 _ authorities said.
Police officials said the arrests of 22 "targets" occurred Wednesday near Paris and across a swath of southern and central France. The suspects were expected to appear before prosecutors.
