(AP) — A problem that caused repeated Amber Alert notifications in the Lawrence area last week has been fixed.

The Lawrence Journal-World reports that Lawrence-area cellphone users heard repeated Amber Alert notifications last week when a 10-year-old Missouri girl was reported missing. But they only received one audible alert Tuesday after a missing Texas teen was thought to be traveling in Kansas.

An official from the National Center for Missing and Exploited Children says the multiple audible alerts last week were a glitch that’s been repaired.

The alerts are shared through a system called Wireless Emergency Alert, which replaced a text message service that required cellphone users to register online and make an adjustment on the phone itself.

The new system sends alerts to all wireless users in an affected area.
