The FBI on Wednesday fatally shot a man holding hostages inside a commercial building in Bakersfield, California, according to the city's police department. 

The 12-hour standoff began Tuesday when police responded to a bomb threat at the Chase Bank building in downtown Bakersfield. The building also houses a school district office, the Associated Press reported. 

Bakersfield police said the suspect was killed in “an officer-involved shooting” involving FBI personnel.

The man barricaded himself inside with several people, two of whom were released after negotiations with authorities. 

All the hostages were later released unharmed.
