(CNN)Two teens were arrested over the weekend in connection with a shooting that wounded three teenagers during a fight in the parking lot of a Colorado high school Friday, authorities said Sunday.
Three 16-year-olds face attempted murder charges after a shooting in the parking lot of a Colorado high school
A third teen was arrested Friday, Aurora police previously said.
"All three that have been arrested are 16-year-old males. Because of this, their names will not be released," police announced in a written statement Sunday night. All three are being held on attempted first degree murder.
The shooting happened around noon Friday in the parking lot of Hinkley High School in Aurora, police said, adding that two of the victims are 17 years old while the third is 16.
A motive has not been revealed in the case, but Aurora Police say they believe more people were involved.
On Monday afternoon, six Aurora Central High School students were shot at a nearby park. The police department is investigating whether the two shootings are related, Aurora Police Chief Vanessa Wilson said.
"These are our kids that are shooting one another," the police chief said. "We have disrespect and no concern for life whatsoever. I need the parents to get involved. I need you checking phones. I need you checking rooms. I need you checking cars. And making sure they are taking away guns from these kids."
In Friday's shooting, an officer with Aurora Public Schools fired back at the shooter before police arrived on the scene, Wilson said.
"We have three juvenile victims at local hospitals. We're trying to work out if some of these individuals may be our suspects or some of these individuals are victims," the police chief told reporters Friday.
Two of the victims shot Friday are Hinkley students, and the third is a student at APS Avenues school. None of the injuries were life-threatening, Wilson said.
The shooting at Hinkley high sent the school under lockdown, police said.
Aurora police also said there had been social media threats to Gateway and Grandview high schools in Aurora, and officers were sent to those schools as a precaution.
