Official: Fake NFL threat competition between two men

A law enforcement official told CNN that a man has admitted he posted a fake bomb threat against National Football League stadiums in major U.S. cities as part of an Internet competition with a person in Texas to create the scariest terror scenario possible.

The official told CNN that it's too early to say whether the man will be charged.

The FBI and the Department of Homeland Security had earlier determined that the threat was a hoax, FBI spokesman Richard Kolko told CNN Thursday.
