INDIANAPOLIS (AP) _ Indianapolis is putting more police in downtown Indianapolis after weekend gunfire outside the Circle Centre mall.
 
  WISH-TV reports the changes being made by Public Safety Director Troy Riggs also include a zero-tolerance policy for lawbreakers who previously might have gotten off with warnings. The changes begin this coming weekend.
 
  Investigators say most of the problems have begun with arguments among teenagers. Officers would disperse crowds only to see the groups meet up in new locations where they sometimes turned violent.
 
  Officers arrested a 16-year-old boy Saturday night after off-duty Marion County sheriff’s deputies saw him fire three shots near the Indiana Convention Center, one block from the mall. The mall is a popular gathering spot for teenagers.
