Pleasanton police say they're following some leads in the stabbing of a Tracy man Sunday after a fracas on Vineyard Avenue.
"No arrests yet, we're still investigating," said Pleasanton police Sgt. Jim Knox. "We do have some leads we're following up on."
Officers responded to several reports of yelling and bottles breaking in the 3800 block of Vineyard Avenue at about 5:40 p.m.
Although officers arrived on the scene within four minutes, no suspects or victims were to be found.
Twenty minutes later, an 18-year-old Tracy man arrived at Valley Care Medical Hospital with a non-life threatening stab wound, according to police.
The victim told police his injuries were sustained at the same scene.
