Police say they have arrested the owner of a suspicious vehicle that was found parked in a judicial center parking lot near the Kansas Statehouse with several homemade explosives and an empty gun holder inside.

Capitol Police Spokesman Patrick Saleh said officers arrested the owner on Wednesday in a nearby state office building connected to the Statehouse by an underground tunnel. He was not armed.

Saleh also said another man was arrested after allegedly phoning in a threat to Gov. Sam Brownback's office from a motel.

But Saleh says the two incidents are unrelated.

The vehicle was found Wednesday morning in the parking lot of the Kansas Judicial Center near the Statehouse.

Saleh says items in the car raised suspicions. Capitol police then called the Topeka Police Department's bomb squad to investigate.
