DENVER (KDVR) — Both lanes of traffic on Interstate 70 near Tower Road were closed Saturday afternoon due to a person with a gun.

The Aurora Police Department had initially told the public that the person was a man, but later told FOX31 that it was a woman.

The Aurora Police Department responded just after 3:15 p.m. and said a man was standing in the median with a gun.

Callers reported that the person was holding the gun in the air, police said.

Officers were working to detour traffic from I-70 as they worked toward a peaceful resolution.

As of 4:01 p.m., the person was in custody, according to APD.

Police told FOX31 that after arresting the person, officers discovered that she was actually a woman. “She was arrested for disorderly conduct and also has underlying mental health concerns,” police said.
