Denver Police closed Interstate 70 at Colorado for a short time Friday as officers investigated a "possible suspicious vehicle."

After about an hour, they tweeted the scene was all clear. One suspect is in custody, police said.

Later, a Denver Police Public Information Officer said the suspect is a woman who told officers she had an "explosive device" in her car.

Police called in a bomb squad who determined there were no explosives in the woman's car. She was arrested for false reporting of an explosive device.

The original tweet from police around 1:00 p.m. said officers were investigating the vehicle in the Stapleton neighborhood.

Stapleton Drive was also closed at Dahlia for the investigation.

I-70 eastbound has since reopened at Colorado.
