Police say a bullet hole found on a window of Acxiom`s downtown headquarters is the third such incident in a year. A high-caliber weapon appears to have created the hole in the window of the unoccupied seventh-floor window. A security guard found the hole on Saturday. Acxiom spokesman Dale Ingram said the company doesn`t believe the shot was meant for someone. The company and the Little Rock police department are putting up more security around the high rise, which was also shot at on July Fifth and on November Fifteenth. One of the four shots fired in November entered the workspace of an employee. Little Rock police spokesman Sergeant Terry Hastings says the shot may have been fired from someone traveling on Interstate 30.
