Six teenagers have been injured following a mass shooting near a Colorado school

The students aged between 14 to 18 have been hospitalised, after being taken to a Colorado emergency medical centre for treatment.

Authorities believe multiple shooters may have been involved in the incident with all suspects remaining on the run.

The students were shot at Nome Park in the suburb of Aurora, just north of Aurora Central High School, where officials set up a secure perimeter and classes were closed for the day.

Speaking at a press conference shortly after the shooting, Aurora Police Chief Vanessa Wilson said multiple suspects had fled the scene on foot and by car, with gang units investigating.

“I have one child in emergency surgery. I want to thank the school resources officers that were first on scene.

“They applied life saving measures in the form of a tourniquet for the individual that’s in surgery now.”

She said it was “very concerning” not only for the city of Aurora, but the nation as a whole.

Drone footage showed the heavy police presence on the scene, with officers walking through the park to seek evidence.

Colorado no stranger to gun crime

Colorado has become a state where gun crime continues to rise. The state has suffered two of the most infamous mass shootings in United States history.

In 1999, two boys shot and killed 12 classmates and a teacher at Columbine High School.

Then in 2012, a heavily armed man stormed a movie theatre in Aurora, murdering 12. The gunman is now serving a life sentence without the possibility of parole.

In March of this year, a gunman killed 10 people, including a police officer at a grocery store in Boulder County, 50 kilometres outside Denver.

Aurora Police Chief Vanessa Wilson says she is “hoping that there’s kids out there that know why this happened. That know what this situation was and can actually share information with us,”
