Sarasota, Florida -- The Sarasota County Sheriff's Office has arrested a 69-year-old Illinois man for exposing himself to teenage girls swimming at Siesta Key Beach.

Around 2:30 p.m., on April 17, a Sarasota County lifeguard alerted deputies to Tom Petcher after two 14-year-old girls said he had his swim trunks around his ankles and tried to brush one of the girls' legs with his buttocks.

As the girls moved away from him, Petcher floated on his back with his genitals exposed.

He continued this activity for at least 15 minutes, swimming toward the girls every time they tried to get away.

When deputies confronted Petcher he was walking quicklytoward the parking lot to try to avoid being detained. He is charged with two counts of lewd and Lascivious Exhibition.
