Convicted sex offenders would face greater restrictions under a proposal from one state senator.

Sen. Scott Price of Bellevue introduced a bill (LB694) on Wednesday that would require sex offenders to get written permission from a school principal or other official to be in a school or on its grounds. The bill also requires permission to participate in school-sponsored activities and athletic events or to ride in any school vehicle taking students to or from such events.

The measure would apply to anyone required to register as a sex offender and who has committed an aggravated offense involving a child.

Violators would face misdemeanor charges.

Sex offenders are already barred from living near schools or day care centers.
