MADRID OFFICE TOWER FIRE UPDATE:

Spanish police investigating the possible arson of the 28-story Windsor office building in Madrid say a home video that provides new evidence is authentic, newspaper El Pais reported, citing unidentified investigators.

Police said images in the video showing two people behind the 12th-floor windows of Deloitte & Touche LLP, the largest accounting company in the U.S. and in Spain, weren't faked, nor were they reflections, the paper reported. The two were ignoring an evacuation order during the Feb. 13 blaze, El Pais said.
