Police officers who responded to what they thought was a robbery of a South Dakota bank found a school tour instead.

Sgt. Dave Beintema told The Daily Republic newspaper (http://bit.ly/1bdNypJ ) that students were being given a tour of the First Dakota National Bank in Mitchell on Tuesday when one of them apparently inadvertently pushed the bank's panic alarm.

Beintema says the group of students found the whole incident amusing.

Mitchell is 70 miles west of Sioux Falls.
