On March 12, 2003 The Chicago Tribune reported that "Villa Park [IL] police today were investigating what appeared to be the latest act of vandalism at the Islamic Foundation, a mosque in the west suburb... About 150 people were finishing prayers at 8:15 p.m. Tuesday when they heard two loud bangs and saw two indentations and a web of cracked glass appear on a window on the northwest side of the building, said Saqib Qureshi, 25, who was among the worshippers... Villa Park Police Det. John Szkolka said police from Villa Park and Lombard and crime lab investigators called to the scene Tuesday night were unable to find bullets or rocks near the window, which measures about three feet wide by four feet tall... Szkolka said he returned to the scene this morning, scanning the area with a metal detector and raking through snow and dirt, but still was unable to find evidence of gunshots... The projectiles failed to penetrate the glass, Szkolka noted, which suggests they were not bullets. He said the attackers might have fired marbles or ball bearings from a sling shot or similar device."
