Officers from multiple agencies combed through evidence at a home in South Seattle after it was raided Tuesday night for explosive materials.
Todd Rogers, 29, was arrested at a home in the 10800 block of Forest Avenue South near Lake Washington after volatile materials were found on the property.
The homeowner alerted police that her tenant might have explosives.
Because it was already dark outside, the materials were left in place and a King County deputy was on watch at the home throughout the night until officers returned at daylight on Wednesday.
The size of the cache of explosives elicited a huge response from law enforcement -- King County deputies and agents from the FBI and Alcohol, Tobacco, Firearms and Explosives swarmed the scene.
The Washington National Guard's 10th Civil Support Team also responded to identify and assess the explosives and advise law enforcement.

Neighbors on either side of the property were evacuated.
Rogers' bail was set at $35,000, though his wife argued in court Wednesday that he was not a threat to the community.
"He is no threat to anyone. He has absolutely no intention of doing anything with these or doing anyone any harm," said Rogers' wife, Kristin Rogers.
But the judge disagreed, calling Rogers "fascination with explosives a remarkable danger."
Rogers said he's not a terrorist and likes to make explosives as targets for shooting.
The King County Sheriff's Office said Rogers has no criminal history.
