Police in Missouri said Sunday that they had arrested a man suspected of abducting a 12-year-old girl he met online.

William Dela Cruz, 22, was arrested in Wentzville, Mo. after authorities issued the alert for Apple Briscoe, of Blue Springs.

Briscoe's aunt told Fox 4 Kansas City that her niece was found unharmed in a diner in St. Louis.

"They have one guy in custody and the other one ran," she told the station.

Investigators are still looking for William Dela Cruz's 24-year-old brother Jason and the silver 2015 Nissan Versa with Maryland license plate number 6CK5071 Briscoe was seen getting into Saturday night.

Police said they believed Briscoe was in danger when they issued the alert.
