Chemical irritant empties Islamic Society of Greater Dayton's mosque Chemical irritant empties Islamic Society of Greater Dayton's mosque By Kyle Nagel Staff Writer Saturday, September 27, 2008 DAYTON â€” Baboucarr Njie was preparing for his prayer session Friday night, Sept. 26, when he heard children in the Islamic Society of Greater Dayton coughing. Soon, Njie himself was overcome with fits of coughing and, like the rest of those in the building, headed for the doors. "I would stay outside for a minute, then go back in, there were a lot of kids," Njie said. "My throat is still itchy, I need to get some milk." Njie was one of several affected when a suspected chemical irritant was sprayed into the mosque at 26 Josie St., bringing Dayton police, fire and hazardous material personnel to the building at 9:48 p.m.
