A Decatur teen remained in the DeKalb County Jail Tuesday following his arrest for allegedly flashing a child at a library.

Johnta Baker, 19, was charged with felony child molestation as well as criminal trespass and two counts of obstruction of officers, according to jail records. He is being held on $53,000 bond.

Channel 2 Action News reported that Baker allegedly flashed a young boy Thursday afternoon at the DeKalb library in downtown Decatur.

A parent and another bystander tried to hold Baker for police, but he broke free and ran to the nearby MARTA station, WSB reported.

Once in the station, he jumped onto the tracks and ran down the tracks into a tunnel. Police blocked the exits to the tunnel, and used a K-9 unit to find Baker, the station reported.
