LOS ANGELES -- A man who police said had guns in his car when he tried to jump a security fence to meet "Dancing With the Stars" contestant Shawn Johnson has pleaded not guilty to stalking charges.

Robert O'Ryan was arrested Tuesday at the studio where the ABC show is produced. Authorities say they found loaded guns, duct tape and love letters in the car he drove from Florida to meet Johnson, a 17-year-old Olympic gymnast.

O'Ryan was arraigned Thursday in Los Angeles Superior Court, where a public defender represented him. Prosecutors charged the 34-year-old with one felony count of stalking and two misdemeanor counts of carrying a loaded gun in a vehicle.

His bail was also raised from $35,000 to $220,000.
