LINCOLN, Neb. (AP) — Authorities on Friday charged Lincoln photographer with manufacturing child pornography and child abuse after finding sexually explicit photos of teenage girls he had taken.

Police said in a news release that Gregory Dightman, 50, photographed underage girls under the guise of paid modeling jobs. Dightman also distributed some of the photos, police said. Police said investigators found the images after executing a search warrant on his home in December.

Prosecutors charged Dightman on Friday with two counts each of generating child pornography and child abuse involving two teenagers. He was being held on $150,000 bond.

Dightman owned a photography business for twenty years called “Fat Boy Photography,” where he photographed individuals as young as 14-years-old, police said. Dightman operated out of a studio just east of Lincoln. Lincoln police continue to investigate and ask the public to contact the department if they believe a child has been a victim in the case.
