A 28-year-old man has been arrested after authorities say he threw two tomatoes at Donald Trump during a campaign stop Tuesday night.

"Andrew Joseph Alemao, 28, was arrested by University of Iowa Police for Disorderly Conduct after he was observed throwing two tomatoes at Republican Presidential candidate Donald Trump during a speech," according to a news release from the University of Iowa.

Alemao was taken into custody by the Secret Service and members of the UI Police Department immediately after throwing the tomatoes at Trump, according to the release.

Trump appeared Tuesday night in front of a crowd of a couple thousand people at the UI Field House. His speech was interrupted numerous times by protesters.

Disorderly Conduct is a simple misdemeanor punishable by a fine up to $625 and/or imprisonment up to 30 days.
