FBI probes PrankNET
PrankNET posts its "greatest hits" on YouTube and streams its calls live on internet radio. Investigators say its creators are difficult to identify due to the diffficulty of tracing prank calls placed online.
Dex, the pseudonym for the group's purported leader, has claimed credit for various expensive scare calls, although others have been attributed to "copycats". The former include one in February to a branch of Kentucky Fried Chicken in Manchester, New Hampshire, in which Dex pretended to be a company boss.
He convinced the staff to douse the restaurant with fire-suppressing chemicals, evacuate the building and strip off their clothes in the freezing cold .
