A rabbi known for anti-child abuse activism in Brooklyn's ultra-orthodox Jewish community had bleach thrown in his face on a Williamsburg street Tuesday, police said.

Rabbi Nuchem Rosenberg was attacked on Roebling Street at about noon, police said.  The bleach attack comes a day after a religious counselor in Brooklyn was convicted of the sustained sexual abuse of a girl in a controversial case that divided the ultra-Orthodox Jewish community in Brooklyn. 

Rosenberg was taken to Woodhull Hospital and is serious but stable condition with burns to the face.  The attack is under investigation, police said.
