A cop in L.A. named Brian Cappell got a call last month about a nine-month-old baby that was choking. And he just happened to be in the right place at the right time.
He was driving in his car about a block away when the call came in. And his chest-cam was on, so the whole thing is on video.
As soon as he heard where the little girl was, he floored it . . . got there in less than a minute . . . and the girl's older sister flagged him down.
Then he grabbed the little girl from her mom . . . started hitting her on the back while holding her face-down in his other arm . . . and saved her life.
Once she started crying, he knew she was okay. He says it was the best sound he's ever heard in his life!
The girl's mom told a reporter that she's eternally grateful for what he did. And they got to see each other again this past Monday when Brian received a commendation for it.
