By Laurie Kellman THE ASSOCIATED PRESS WASHINGTON – U.S. Capitol Police reported four fires in Senate office buildings Wednesday. All were extinguished by midafternoon, but an investigation continued. “They are suspicious in nature,” said Sgt. Kimberly Schneider. She said two fires in the Dirksen Senate Office Building and one in the Hart building next door were reported in women’s bathrooms and were extinguished between 10:45 a.m. EDT and 12:30 p.m. A fourth, also in a Dirksen restroom, was reported later and extinguished by midafternoon, Schneider said. There was at least one other similar fire last week in a Senate office building bathroom that was determined to have been caused by a cigarette, according to a knowledgeable Senate official who is not authorized to speak to reporters and demanded anonymity. Capitol Police sent out a mass e-mail noting “a series of small fires that have occurred in the Senate Office Buildings in recent days,” and asking for tips. The e-mail said that more building patrols have been added to investigate.
