BROOKLYN - A Brooklyn grandmother says she was horrified to find a video she rented at a local library was overdubbed with pornography.

Esther Klein says she rented an Austin Powers movie from the Brooklyn Public Library only to find a pornographic video overdubbed on the tape. Klein says she rented the movie for her grandchildren, but watched it first to make sure it was appropriate.

A library spokesperson says 18 tapes were tampered with in January and the police investigated and arrested a suspect. The spokesperson says this is the first tape found with pornographic material since the investigation.
