Three men were rescued Friday morning after they became trapped in the sub-basement of a downtown Appleton bar. At about 1:50 a.m., the Appleton Fire Department was called to The Durty Leprechaun, 343 W. College Ave., for a report that a stairwell had collapsed and trapped three men in a sub-basement, the department said. When firefighters arrived, they found the stairwell to the sub-basement — 25 feet below the basement of the building — had broken and trapped the men within tight confines, according to the department's news release. After an attempt to use a ground ladder and an alternate staircase in a neighboring structure failed, department personnel utilized a rope pulley system, which allowed a firefighter to be lowered into the sub-basement, the release said.
