According to WPXI-TV, police said Juwan Mitchell, 22, lured the girl away from her grandmother's Northview Heights home and raped her.
The girl told officials she was outside of her grandmother's home on Hazlett Street when a man approached her, according to the criminal complaint.
According to court documents, the girl said the man told her he was her uncle, and asked her if she wanted to go to the store with him. But instead, she said, Mitchell took her into the "basement bathroom" of an "unknown residence" and raped her, according to police.
It's not clear from the complaint how long the girl was away from her family or how she was returned home.
According to court papers, Mitchell was identified on surveillance video. Police said they know it's him because they've dealt with him several times before.
