Man arrested after threatening to blow up Democrats' office in US

Police have arrested a man in Spokane, Washington, Wednesday morning after he allegedly entered the county Democrats' headquarters and threatened to blow it up.

Authorities said the man entered the Teamsters building, located at Indiana and Division street, wearing a backpack with wires sticking out, saying he had a bomb.

Police said they then surrounded the building and apprehended the suspect without incident as he exited the headquarters. The suspect was not wearing his backpack at that time, according to the Spokane Police Department.

As officers entered the building, they noticed smoke coming out of an office. After making sure the building was evacuated, police called in the bomb squad, which determined the backpack was not explosive.

Police said the man did start a fire inside the building, but no one was injured in the incident.
