Aurora, CO, Police early Sunday morning said 600-800 cars were intentionally blocking officers from accessing southbound Interstate 225 where there were reports of people racing and waving weapons.

The tweet, which went out about 12:08 AM, reads: "There are reportedly 600 vehicles involved intentionally blocking the shoulders preventing police from accessing the area. There are reports of fireworks and smoke and weapons being waved. Stay out of area while officers try to address the situation."

City Council members say street racing has been an ongoing issue in Aurora and the surrounding metro for years, noting a proposal is in the works to help combat the problem, KDVR reports. 

In February, street racing was brought up at Aurora’s Public Safety Policy Committee meeting; according to local lawmakers, police said they are looking into both local and state legislation to help stop the issue.
