A 17-year-old boy is in critical condition Monday morning at a Dallas hospital following an early-morning altercation that started in the drive-up window of a fast-food restaurant, police said.
The incident began shortly after midnight at the restaurant near the intersection of Marsh Lane and Trinity Mills Road in far north Dallas, according to reports.
Police aren't sure what prompted the argument between the people in two vehicles in line, but obscene gestures were flashed and then words were exchanged, said Senior Cpl. Jerry Monreal, police spokesman.
The people in one vehicle drove from the restaurant to a nearby parking lot, and they were followed by the other vehicle, a red Jeep Cherokee carrying a man and a woman, Monreal said.

Everyone got out of their vehicles but the man from the Jeep had a knife, Monreal said. The 17-year-old was stabbed in the chest and one of his friends was cut, Monreal said.
"Both of the injured people ran back to their vehicle and decided to drive to the hospital," Monreal said. "But one of them saw that his friend was bleeding too much, so they decided to pull over and call for an ambulance."
They stopped, Monreal said, and as they did, the Jeep pulled up and the woman got out and threw some rocks at their vehicle.
"Then they took off," Monreal said.
The 17-year-old was in critical condition and his friend who was cut was in serious condition, both at Parkland Memorial Hospital, Monreal said.
Police were looking for the two people in the Jeep, but no other information was available Monday morning.
