Police with the 83rd Precinct said a man snuck into an apartment on Melrose Street and Central Avenue in Brooklyn through a window and groped a sleeping woman.

It happened just before 4:30 a.m. Tuesday, and it left some residents in this gentrifying neighborhood a little rattled.

"Bushwick's a really great area and I love it. I think this could have happened in any area," one local resident said. "A good reminder for everyone to be careful."

"It doesn't surprise me, really," said another.

Investigators said the man touched the woman's buttocks and groin area, and when she woke up, he fled through the same window he entered.

They also said surveillance video was taken in the area on the same night of the incident. More photos of the man showed he was wearing dark clothing.

The incident occurred in the middle of an unseasonably warm stretch of weather that had many folks opening their windows at night. Police said New Yorkers may want to think twice about that, noting that the attacker entered the victim's apartment through an unlocked first floor window.

"My particular building and my particular apartment are pretty secure, so I'm not specifically worried about it," one woman said. "But, yeah, I could see there being a concern for these smaller buildings that have easier access."

Police said the man, believed to be in 20s or 30s, got away in a blue 2015 Toyota Camry.
