Suspects in connection with chemical attack on Arvada officer ID'd

ARVADA, Colo. (KKTV) - Five teens were arrested last weekend after allegedly throwing a bottle containing some sort of chemical gas at an officer, causing him to pass out.

Sister station KCNC says the Arvada police officer had responded to a call on April 6 about traffic signs stringed together with plastic wrap. While looking over the debris and talking with the bystander who had called in the report, one of the suspects reportedly yelled something at the officer and then threw a bottle at him. Smoke began to drift out of the bottle, then the officer smelled chlorine and was knocked out. He was taken to the hospital and later released. The other person at the scene was also injured but able to be treated at the scene.

A Walmart receipt found in a nearby field led investigators to the teens on April 7. Four of the five teens are over 18 and are facing charges of possession of a chemical, biological or radiological weapon. They were identified Saturday as 19-year-olds Gavin Dawson, Isaac Koch, Braiden Ulmer and 18-year-old Maxwell McCann. It's unclear what charges the individual under 18 will face.
