CHP officials evacuated the Homewood Suites and blocked off several blocks of the Embarcadero as they looked for explosives.

The CHP said the search stemmed from an investigation following an arrest of a man by CHP on Sunday in Alameda County.

The bomb squad searched a room associated with that arrested man, as well as his pickup truck, parked outside the hoel.

Oakland police assisted the CHP with securing the perimeter and traffic control only, police said.
