Jake Brahm, accused of posting false information that dirty bombs would be detonated at seven stadiums having games on Oct. 22, 2006.

NEWARK, N.J. - A man has pleaded guilty to making bogus Internet postings warning of terrorist attacks against NFL stadiums.

Jake Brahm admited in federal court in New Jersey that he posted false information that dirty bombs would be detonated at seven stadiums having games on Oct. 22, 2006.

The 22-year-old Wisconsin man had said the stadiums were in Miami, Atlanta, Seattle, Houston, Oakland, Cleveland and New York City.

He admits that the reference to New York City was intended to indicate Giants Stadium, in East Rutherford, N.J., where the New York Jets played the Detroit Lions that day.

Brahm remains free on bail and faces up to five years in prison and a $250,000 fine when sentenced June 5.
