KENNEWICK, WA - During the month of April, 2017, the Benton County Gang Team conducted an investigation into an assault that had occurred in early February, 2017.

PASCO, WA - A road in Pasco is back open after Pasco Police closed it to allow the Benton County Sheriff's Office and SWAT execute a search warrant. Several streets near 3rd and Columbia closed down Monday evening.

The warrant goes back to an investigation in Benton County, apparently the building has been a problem in the past. Officers tells NBC Right Now SWAT team came in as a precaution.

Sergeant Scott Warren says, "I don't know if it's exactly abandoned per say, but people have broken into it, gotten into it, and made their homes out of it, stuff like that. So, I think that's probably part of the issue here with this case."

We've called the Benton County Sheriff's Office to try and find out details about the case, but haven't gotten any more information.

This is a developing story.
