The Regional Street Enforcement Team arrested 30-year-old David Hermes last night in Sun Valley.
They say he was leaving his friend's trailer home when they boxed him in with their police cars.
Hermes had no drugs or weapons on him...but officers say they found 43 explosives, 10 weapons, methamphetamine, and marijuana inside his apartment.
That search, Wednesday night, led to an evacuation of the apartment complex while a bomb robot looked inside.
The SET team says Hermes has a criminal past which includes a battery with a deadly weapon charge.
They say he was dealing weapons and drugs to other criminals in Northern Nevada.
Part of their ongoing investigation will include where this illegal stuff was coming from and if he was allegedly working with someone else in state or out of state.
