An intruder slipped through the first floor window of a Great Neck home and into the bedroom of a sleeping 15 year old girl who woke up early Sunday morning to find the man straddling her.

"She woke up, she found this person sitting on top of her holding the rag to her face," said Nassau County Police Detective Kevin Smith.

The girl managed to fight back, startling the intruder who ran out of her room and fled through a back door, police said.

After he left, she ran upstairs to alert her mother and when they walked down to her ground-floor room, they saw the same man reaching through her window, Smith said. It is possible that he was trying to recover a wet rag and a black or dark-blue baseball cap with an embroidered eagle and American flags that Nassau police later found in the room.

The attempted abduction occurred just before 5 a.m. Sunday morning, and the victim and her family were too upset to talk about the ordeal.

Police are examining the rag for forensic evidence and to see if it contains any chemicals like chloroform.

It's unclear what the man's motive was, and police are investigating any connection to a similar break-in last year in Great Neck where a teenage girl was sexually abused.

The male suspect in this case was described by the victim as 5'8" tall with curly brown hair.

Police are urging people to lock their doors and windows.

Police ask anyone with information to call Crime Stoppers at 800-244-TIPS. Callers may remain anonymous.
