Seattle Fire Department spokesman David Cuerpo told news outlets that around 25 people were evaluated for injuries after the 4-foot-high steel barricade collapsed on Aug. 31 at the Seattle Center, which was playing host to the Bumbershoot Music & Arts Festival. Electronic music artist Jai Wolf was performing at the time.
Four people were hospitalized with minor injuries.
Cuerpo said members of the crowd of around 3,000 people were pressed against the barrier, causing it to fall. Wolf canceled the rest of his set.
The festival said in a statement that on-site medical teams assisted those injured.
