Des Moines police plan to set up a special phone tip line that students can use to help officers keep weapons out of schools.
Des Moines Police Chief Judy Bradshaw told the City Council recently that the department wanted something "to sell to students."
The line will operate through the Polk County Crime Stoppers program. If the tip proves accurate and useful, the tipster might receive a reward.
Since 1995 a similar line in the Davenport area has generated calls about drugs, weapons and vandalism of school property.
Bradshaw unveiled her plan for the council during a presentation on gun violence and what the city is doing to prevent it and how the city would respond if it were to occur.
