An undercover officer was investigating an ongoing lewd activity at Mohawk Park Friday afternoon.
It didn't take long for the officer to find it.
Police say the officer went to a pavilion in the northeast part of the park. A short time later, 26-year-old Michael Hamsher approached the officer.
He's accused of exposing his privates and touching himself. This was happening in "full view of the public."
Hamsher backed into the southeast corner of pavilion and the lewd activities began.
Hamsher was then arrested and taken to the Tulsa County Jail. He faces a count of indecent exposure.
