INDIANAPOLIS — Indianapolis is preparing for the Indiana Black Expo summer celebration.

The 10 day event is expected to bring in over 30,000 people and a more people means a bigger police presence.

Indianapolis has dealt with violence over previous expos and has already had several deadly shootings in the last few weeks.

Now police are bringing in extra lights, cameras, and officers as well as a new Crimestoppers tip line.

"You see a large group starting to gather, starting to cause an issue, you see somebody place a bag down next to a building and runaway from it - you can contact us," said Indianapolis Homeland Security Chief Gary Coons.

Indianapolis police are even bringing in some unusual backup pastors.

They plan to help talk to younger people on the streets and break up large groups to avoid violence.
