SIOUX FALLS, S.D. (AP) - Sioux Falls police responding to a call about a juvenile carrying a gun inside Empire Mall says the person had a non-lethal pellet gun.

No one was hurt, and the unnamed juvenile is being questioned.

Police Lt. Terry Mixell says someone from the mall called police Friday afternoon. By the time officers arrived, the juvenile was gone, but they were able to track him down nearby.

Mixell says the Airsoft gun shoots plastic pellets.

Tensions nationwide have been high since last week, when a gunman opened fire in an elementary school in Newtown, Conn., killing 20 children and six adults.

This Friday also marks the day that some believe ancient Mayans had prophesized the world would end, which has prompted threats that closed down smatterings of schools across the country.
