HILLSBORO, Ore. - A group of men unloaded a half-dozen gunshots at an 18-year-old at a Hillsboro park Saturday, striking him in the leg and shooting up several vehicles in what police believe may have been a gang-related shooting.

It happened shortly after 3 p.m. when four to five men in their late teens or early 20s were standing in the center of Walnut Street Park and fired about seven rounds from .22-caliber and .45-caliber handguns toward the victim, who was standing on the sidewalk near the park, according to Lt. Michael Rouches, a Hillsboro police spokesman.

One round hit the 18-year-old in the upper left leg area while others shattered the windows of two nearby vehicles, Rouches said.

The teen was taken to Oregon Health and Science University for treatment of non-life threatening injuries, he said.

The shooters fled the area, possibly in a tan GMC sport utility vehicle, Rouches said. 

Members of the Washington County Inter-agency Gang Enforcement Team responded to help Hillsboro detectives in the investigation.

Southeast Walnut Street was closed between Southeast 16th Avenue and Southeast 18th Avenue for about five hours following the incident, Rouches said.
