[i]JACKSONVILLE, Fla. - Thomas Florence has a knot on the side of his head from what appears to be another round of the "knockout game," something happening across the country in which the object is to try to knock someone out in one punch. It happened twice in Arlington on Tuesday. Thirty-one-year-old Florence went to Walgreens on Merrill Road at Townsend Boulevard in Arlington to pick up diapers and medicine. On the way out, he stopped at a Redbox. Florence said he was looking at what movies to rent and was fixated on that when all of a sudden he saw someone out of the corner of his eye. The next thing he knew, that person punched him right in the side of the face. "I was kind of stunned for a second," Florence said. "I didn't realize what was going on. And then I ran after them." He said it was four teenagers, one of whom had a white puppy. He raced inside the store and told the cashier to call 911, then jumped in his truck after them. Florence said he spotted the kids near Terry Parker High School and did a U-turn, but they were gone. Police say the incident mirrors a recent similar one at a Hess gas station nearby, also involving four teens and a white puppy. One of the teens punched a disabled man one time and they ran away...[/i]
