Police took 20-year-old Isiah Tyrek Bogan into custody around 11:30 a.m. Wednesday after a traffic stop not far from the Forestville apartment building where the alleged assault occurred.
Last Wednesday, investigators say Bogan followed the 12-year-old girl onto an elevator, then forced her to the ground and sexually assaulted her.
Police say the victim's mother encountered the suspect two days later. She lunged at the suspect and forced him to the ground. He managed to get away before police arrived.
Bogan is charged with several sex offenses, second degree assault and additional charges.
