What would you do if your bike was stolen right in front of you and you couldn't do anything about it?
Nukia Weaver, 10, said her brand-new bicycle was stolen while she was riding it for the first time.
"I didn't yell anything," she said. "I was in shock, thought I was having a dream or something."
But the responding officers decided to pitch in and replace Nukia's bike, which had been a birthday gift.
"I guess, for us, to think that a guy would steal a bike from a little girl and just take off -- that's what made me want to buy the bike," Officer Paul Hernandez said.
Nukia, a fourth-grader, said the thief pulled up in a car and took the bike while she and her friends were on a water break.
"He just put it in his trunk, and he drove off," she said.
Nukia ran home and told her mother, who reported the theft to Dallas police.
"I was thinking, 'Why would anyone do that to, like, me? Because I'm a very good person,'" she said.
"I started screaming, and I started jumping up and down, and I was like, 'Oh my God, Mom, they bought me another bike!'" Nukia said.
She said it makes her new bicycle even more special.
"But it's kind of special because a policeman bought it," Nukia said. "And who would think a police would buy it for a little girl?"
She said she will keep the new bike in the house so no one can steal it.
Police are looking for the man who stole bikes from Nukia and another child in the Dallas area.
