Mr. Michel Rosenzweig was arrested by the Montgomery Country Police Department and charged with five counts of third degree sexual assault from an incident in 2003.
Mr. Rosenzweig was a part-time phys. ed. teacher at St. John the Evangelist School (Silver Spring) from 1989 to 1992. Therefore, his arrest is not related to his employment with the Archdiocese.
However, this linked video states that he was accused in 1990 of inappropriately touching several female students, which would have been the time he was employed by the Archdiocese. But, according to the video, police could not charge him because "there was not any probable cause."
If you have any information, please contact Det. John Reinikka of the MoCo Family Crimes Division (1-240-773-5400).
Update: It seems that SNAP has weighed in on this matter. If you go to their website, you can see how they have left out facts, such as the fact that the was also a teacher in other private schools and public ones, and worked for other organizations. Personally, I don't trust SNAP but that is just me.
However, I will fault the Archdiocese for not having ANYTHING on their website (as of this writing) about this issue. You thought that they would have learned.
