An elevator repair man was killed when he plunged six stories down a shaft while working inside a halfway-house for convicts in Bedford-Stuyvesant.

The unidentified worker was servicing the elevator on the top floor of the six-story building on Myrtle Avenue near Marcus Garvey Boulevard about 9:30 a.m. today when he fell to the basement, said fire department sources.

The worker was pronounced dead at the scene.

The building is home to the Brooklyn Community Correctional Center, a privately run, minimum security residential housing facility for non-violent offenders, which provides job training prior their release from detention, according to the organizations website.

The victims name was not released pending notification of his family, said cops.
