HARTFORD, Conn., June 30 (UPI) --
Hartford, Conn., police closed part of a street and evacuated a city hall floor Wednesday after a worker reported finding a suspicious substance.
A spokesman for Mayor Eddie Perez said the FBI ordered the first floor of the city hall evacuated after the substance was found, the Hartford Courant reported.
