NORTHGLENN, Colo. -- The FBI participated in a raid of home in Northglenn that lasted all day Friday.
The neighborhood in the 11700 block of Grant Street was blocked off by law enforcement beginning early Friday morning.
"It is quite a spectacle. I've never seen anything like this," one resident said from the inside of his vehicle.
FBI investigators dressed in hazardous materials suits and respirators spend all day going through the house.
Sources told FOX31 Denver investigators came looking for a meth lab. They did find evidence of the drug, but no meth lab.
The FBI says their search was extensive. We don't know what else they were looking for.
Police did arrest Richard Jackson. He has a long criminal history and some neighbors said they weren't surprised he was led away in handcuffs. "There's always cops there all the time," one said.
The FBI has not released any other information about what investigators found inside the house.
