The victims at East High School included two boys and one girl, according to fire department spokesperson Ahman Douglass.
The gunfire appears to have come from a passing vehicle, police said.
Police started getting calls around 2:48 p.m. CT (3:48 p.m. ET), said police Sgt. Paul Parizek. A news release from Des Moines police said officers received multiple calls reporting gunfire at the school and multiple injuries.
Upon arrival, police found the three students all with gunshot injuries. All were taken to area hospitals.
Police detained potential suspects, Parizek said. No charges have been filed at this time, the release said.
“Des Moines Police and DMPS public safety have given East High School the all clear. Students are dismissing on time,” the school district tweeted.
CNN is reaching out to the school district and the police department for more information.
This is a developing story and will be updated.
