Two kayakers were out on the water at the Arboretum when they say that a man exposed himself to them.
On Wednesday, Dayo Vice and her friend were about to turn a bend in the Foster Island Loop Trail when she said a man emerged out of the brush.
Vice said the man exposed himself, waved and laughed at them.
Immediately after, they called 911 to report the incident.
"And when we said we were gonna call the cops, he jumped into the bushes," Vice said.
Police are still looking for the man.
