Chicago ramping up security at Lollapalooza music festival

CHICAGO (AP) - Chicago Mayor Lori Lightfoot is promising a "robust security plan" to protect patrons at this weekend's Lollapalooza music festival.

Lightfoot's promise Monday came a day after a shooting at a California food festival that killed three people and wounded 12.

Lightfoot says she'll participate in an exercise Tuesday to test the security plan put together by Chicago police and Lollapalooza organizers. The newly elected mayor says the city is drawing upon federal resources to ensure there's no incident in Chicago.

Chicago's Office of Emergency Management and Communications notes in a statement that each year, tighter security measures are implemented, including elements that are seen and unseen.

Chicago police beefed up security last year in the wake of the October 2017 mass shooting at a country music concert in Las Vegas.
