CHICAGO (AP) - Chicago authorities say a 25-year-old man has been charged in last month's brutal beating and sexual assault of a teen-age girl on the city's northwest side.

The Cook County State's Attorney's office says Luis Pantoja is charged with attempted murder and sexual assault in an attack on a 15-year-old girl on the morning of Dec. 17.

Authorities say he was arrested on Friday and is expected to appear in court later Sunday. Police planned to release more details at a news conference

A resident going outside to sweep snow found the girl lying in a pool of blood with her pants and shoes off in his backyard in the city's Belmont-Cragin neighborhood.

Authorities have said the girl suffered severe head injuries, but was able to communicate last week.
