Update: 11:55 p.m. UATV reporter Katie Simms appears to be providing live coverage on Twitter (@ksimmsua). According to Simms, the man is still on the ledge.
University of Arkansas Police are attempting negotiations with a possibly suicidal man who is sitting on a ledge atop the Garland Center parking garage on Garland Avenue in Fayetteville.
UAPD spokesman Lt. Gary Crain said the man has so far been unresponsive to negotiators since police first responded at about 4:45 p.m.
As of 7 p.m., no streets had been blocked off, but authorities were working to keep crowds of onlookers from congregating below the scene.
