BLOOMINGTON, Ind. (AP) _ Bloomington and Indiana University police say they’ll be extra vigilant during this weekend’s Little 500 bicycle races in response to Monday’s deadly explosions at the Boston Marathon.
 
  Bloomington Police Chief Mike Diekhoff says his department began talking with IU authorities following the Boston bombings and now has “additional plans that have been put in place.”
 
  The Herald-Times reports Diekhoff said Tuesday that some of those plans include a stronger police presence at the outdoor bicycle races, but he declined to give specifics.
 
  IU interim Police Chief Laury Flint says that aside from the heightened police presence at the weekend races and other Little 500 events it’s important for anyone who notices anything suspicious in Bloomington during the weekend events to report that immediately to authorities.
