Bomb threat reported at government building in Kansas City

A suspicious vehicle is being investigated in downtown Kansas City after police said a man walked into a government building and said he was a terrorist.

Kansas City police sent a robot to investigate the man's car Friday after a bomb-sniffing dog detected some sort of explosive in the vehicle.

The vehicle was parked on a street between the Richard Bolling Federal Building and the Fletcher Daniels State Office Building. It wasn't immediately clear which building the man had entered around noon Friday.
