SANFORD, Fla. -

Sanford police arrested a man who they say was performing lewd acts on himself in a church office.

William Knox, 43, was charged with indecent exposure last week after two victims spotted Knox at City Church inside of an office with the door locked looking at pornography, according to a police report.

The victims said Knox saw them, and continued to to perform lewd acts on himself. A pastor came and removed Knox from the room, according to the report.

Knox told investigators he didn't think anyone else was present. He was taken to the Seminole County Jail.
