A 29-year-old woman was heading inside her home when a man approached her from behind.
He reached under her dress and groped her.
She wasn't hurt, but she was taken to a local hospital to be checked out.
"It's the aggression at women that's outrageous and unacceptable," said neighbor Richard Lane.
The man responsible for these groping incidents is the subject of wanted posters in Carl Shurz Park.
There's a $2,000 reward for information leading to his arrest which many hope happens soon.
"It's kind of disturbing. Hope you're safe in your own neighborhood and you hope they find him and get him," said neighbor Katie Wanner.
