KEARNEY, Neb. (AP) — Nebraska officials say 13 teenagers are awaiting discipline after escaping a youth rehabilitation center in Kearney.

The state Department of Health and Human Services says two teens left on foot Saturday night from Kearney’s Youth Rehabilitation and Treatment Center. An additional 11 teens followed.

Additional staff and Kearney police were called in to help apprehend the youths. The last escapee was returned to the center hours later.

Department spokesman Russ Reno says the youths took key cards to leave the center. Additional information about the circumstances of the escapes was not released.

Reno says the Buffalo County attorney will determine if the youths will be charged criminally. One 18-year-old escapee was arrested on a warrant for failure to appear in court.
