Police have cleared a man initially suspected in the sexual assault of an autistic 17-year-old girl in Brooklyn, officials said Saturday.

Cops took the man into custody in his home around 2 p.m. Saturday. Members of the NYPD’s Special Victims Unit interviewed him and determined that he was “credible and cooperative,” police sources said. He was then released.

The teen had just gotten off a bus at a wrong stop in Park Slope early on Thursday when her assailant noticed her confusion and asked if she needed help, according to cops.

The creep took the disoriented girl into a park and assaulted her around 1 a.m., officials said.

The girl was found 11 hours later in the chapel at Methodist Hospital, police said. It was not clear when or how she got there. She was admitted to the hospital in stable condition, according to investigators.

There were no suspects in the case on Saturday afternoon, police said.
