Santa Clara police have arrested a San Francisco man on child molestation and battery charges after three underage girls reported that he groped them in a pool at the Great America theme park earlier this month.
Police believe that Siegfried Gramatzki, 64, who also goes by the name Frederick Stein, touched and groped three girls, ages 10, 15, and 17, as they swam in the pool the evening of June 6.
Park security officers detained Gramatzki until police arrived.
He was released after posting $50,000 bail and is scheduled to be arraigned on July 6.
Gramatzki did not know the girls, according to police.
Anyone who knows Gramatzki or who may have witnessed the incidents is asked to call Detective Sgt. Craig Middlekauff at (408) 615-4823.
