A man climbed through a window at a home in the South Shore neighborhood early Sunday morning and sexually assaulted a 9-year-old girl sleeping inside, according to police.
It happened in the 2500 block of East 72nd Street, according to police News Affairs Officer Darryl Baety.
The girl was apparently left at home alone while her mother was at work, when the man climbed through a window, said Baety.
"He sexually assaulted her and then when she woke, he fled the scene," said Baety.
The child was taken to a hospital.
No one was in custody late Sunday morning. Calumet Area detectives are investigating.
