The authorities arrested a man they said had slashed a giant balloon of a baby Donald Trump that was on display to protest the president’s visit to a football game in Alabama on Saturday.

The man, Hoyt Hutchinson, 32, was arrested after officers in Tuscaloosa, Ala., saw him cut the balloon and then try to flee at about 1 p.m. on Saturday, the police said on Facebook. It wasn’t clear what Mr. Hutchinson had used to slash the balloon.

“I am going down here to make a scene, so y’all watch the news,” Mr. Hutchinson said in a Facebook Live video before the game.

The balloon, which stands 20 feet tall and 13 feet wide when fully inflated, had been set up at a protest at Monnish Park. Mr. Trump attended the game about a mile away at Bryant-Denny Stadium to watch the University of Alabama and Louisiana State University face off.
