Lil Baby’s back-to-school event in Atlanta, Georgia was canceled due to the heat.

According to the Atlanta Journal-Constitution, the rapper’s event took place on the afternoon of Aug. 7 at the West End mall in Atlanta. Atlanta fire officials were called at approximately 2:30 p.m. due to people standing in the heat for hours without water and becoming ill. Six people got sick and one was hospitalized after having a seizure, the outlet reports.

It’s unknown when the event was canceled but it was scheduled to go on until 6 p.m. The temperature was 90 degrees.

Hundreds were expected to attend the Atlanta native’s Back-to-School Fest, which included music, games, carnival rides, free food, backpacks, school supplies, and free haircuts. Lil Baby was providing shoes and clothing from Foot Locker Atlanta for every child who arrived. It’s unclear how many families attended the event before it was canceled.
