NASHVILLE, Tenn. (AP) — Authorities say eight juvenile delinquents are still on the run after a mass breakout from a detention center in Nashville overnight.

Tennessee Department of Children's Services spokesman Rob Johnson said Tuesday that 30 teenagers escaped from the Woodland Hills Youth Development Center after breaking out of four different locked dormitories late Monday night.

The on-duty staff initially thought the teens were contained in the yard, but called police after they realized that juvenile offenders were escaping under the fence.

Most of the teenagers at the center have committed at least three felonies.

By late Tuesday most were back in custody. Some were turned in by their families for their own good.
