GREEN TOWNSHIP, Ohio -- A Green Township neighborhood is on high alert after an intruder broke into a house and sexually assaulted a 15-year-old girl.

Police said she was dragged from her house and sexually assaulted in her back yard.

Neighbors near Starhaven Trail said she was choked and passed out for awhile before she was able to get back to her house, NewsChannel5 sister station WCPO-TV reported.

"Very rattled," said neighbor Jennifer Wibbelsman, who described her emotions. "We just moved here in August. You know, you like to think you're in a safe neighborhood. It happening this close really rattled me."

The attack happened in mid-October, but Green Township police did not release an exact date.

In fact, police are currently very tight-lipped about the case except to warn neighbors to be on alert.

"Really startled me. I was up and getting ready to leave for work shortly before that time," said neighbor Ryan Keller.

Keller said that the neighborhood is organizing a block watch program.

"I'm hoping to be involved in that," Keller said.

Police said this attack may be related to a similar one that happened in the neighborhood in March.

At that time, a 20-year-old woman was assaulted as she walked to her car. Police said she was dragged between two houses and threatened with a weapon.

Police are urging neighbors to report anything out of the ordinary.

They are also encouraging residents to leave their lights on and keep doors locked.
