Cincinnati police officers are following up on a promise made to a child on his birthday earlier this year.In June, we shared the story of 6-year-old Carter.Police said Carter's grandparents adopted him when he was little. His grandparents told police they feel bad that they can't play with him as much as they want due to their age.You can watch Carter's full tour in the video player above. Also, the children Carter's tried to play with in their neighborhood haven't been the kindest to him, his grandparents said.So for his birthday, Carter's grandparents took him to Cincinnati Police District 3. He was greeted by two police officers who told him that they were so excited to meet him.The police department made Carter an honorary police officer for the day."We expect you to act like we do, and we want you to behave for mom and dad the rest of the day," an officer told the child.Carter was given a tour of the District 3 headquarters and he was shown their radios.Officers told him for his birthday, they presented him with a certificate that rewarded him with a police car ride back to school and he redeemed that certificate Friday. Carter started kindergarten and was dropped off by Cincinnati officers."Everyone wish Carter a great school year!" CPD said in a post.
