A building at the University of Central Florida in Orlando has been evacuated after campus police say someone wearing a LeBron James Miami Heat basketball jersey stood up in a classroom and threw powder in the air.
UCF police said in a statement posted Wednesday on Twitter that the Business Administration building was evacuated "out of an abundance of caution." In a video posted on Twitter, Police Chief Richard Beary said it appeared to be a stunt but they had to treat it as an emergency.
Campus PD gave an "all clear" after the substance has tested positive for powdered baby formula.
James, who now plays for the Cleveland Cavaliers, sometimes tosses chalk in the air in a pregame ritual.
Police said they're seeking a second person who was seen carrying two backpacks.
