Police are asking for help finding a man accused of raping a 12-year-old girl in Brooklyn after bursting from her shower.

Sources say the man was carrying a knife when he sexually assaulted the girl back on March 5.

They say she was alone inside her home on Remsen Avenue and Farragut Road in Canarsie, when she went to the bathroom, and the man jumped out from behind the shower curtain.

Neighbors tell us they are concerned.

"That's devastating," one said. "Like I said, this area here is fairly quiet. You have working class, hardworking people. So for something like that to happen is a little crazy."

"I feel terrible because I have an 11-year-old granddaughter and sometimes she walks by herself," said another neighbor. "It's crazy."

Sources say the man was wearing nothing but a ski mask and winter gloves.

He's believed to be between 5-foot-4 and 5-foot-8, with a Caribbean accent.
