Police chief: 'It makes me angry'

According to police, five of the victims were taken to the hospital to receive medical treatment for their injuries. One person did not want to go to the hospital. Their conditions were not immediately provided.

"It makes me angry, I am mad, I am pissed off," Fort Worth Police Chief Neil Noakes said to reporters at the press conference. "There’s absolutely no reason anybody should be conducting themselves in such a violent, careless, heartless way that children should be shot."
