UPDATE:   KANSAS CITY, Mo. – Authorities spent Friday afternoon looking for explosives inside the vehicle of a man who walked into the Kansas City federal building and asked about a terrorist watch list. He is currently in police custody.

The man entered the Richard Bolling Federal Building, 600 E. 12th St., around noon and asked authorities if he was on a terrorist watch list, according to the FBI.

Although the suspect, whose identity has not yet been confirmed, never made any threats, authorities detained him and searched his vehicle.

The Kansas City Police Department ordered the bomb and arson squad to his vehicle, located in the Fletcher Daniels State Office Building parking lot, 615 E. 13th St. A bomb-sniffing dog then detected the presence of explosives, prompting evacuations at the state office building.

Just before 5 p.m., authorities confirmed that no explosives were found in the vehicle. A temporary flight restriction issued for downtown Kansas City was lifted shortly after. Police reopened the streets, which were closed for most of the day, just after 5 p.m.

State office employees were cleared to leave for the day. The federal building was also closed for the day for precautionary reasons, according to authorities. Earlier, children in the day care center at the federal building were evacuated to a pre-approved off-site location.

The man entered the Richard Bolling Federal Building, 600 E. 12th Street around noon Friday.

KSHB-TV reports the Kansas City Police Department ordered the bomb and arson squad to his vehicle, located on the northeast corner of the building, near 13th and Holmes.
