MONROE, Mich. -

Authorities say they've apprehended two teenage girls who escaped from the Monroe County Youth Center in southeast Michigan.

The Monroe County sheriff's department says the 16 and 17 year olds were part of a work program that allowed them to be outside the locked facility about 35 miles southwest of Detroit to care for animals.

They were reported missing Monday evening in a call to 911. The sheriff's department says they were found about an hour later trying to use a phone at the home of an area resident.

A tracking dog and sheriff's department helicopter were used in the search. The sheriff's department says the girls are expected to face charges in the escape.
