Three students — two found with guns, the other with some kind of device — are in custody after causing a one-hour lockdown at a Denver middle school. No one was injured.

Police say students reported the boys Friday to officials at Skinner Middle School, but officers didn't immediately release details about why they had the weapons and where they were found.

Police originally said the third student had a smoke device but later said they were still investigating what exactly it was.

The school was open after the lockdown, but some parents arrived to take their children home. The scene was calm, with families periodically leaving the school along with police investigators.

One officer carried out a backpack in one hand and a paper bag in the other.
