Authorities arrested two people suspected of re-enacting the amorous behavior that led to the baby boom in the World War II movie theater at the State of Nebraska Historical Museum on Thursday.
A security officer watching the museum's cameras told police he spotted a couple having sex at 2:55 p.m., Lincoln Police Officer Katie Flood said.
"He walked to the room to verify, heard sounds consistent with sexual intercourse, retreated and called LPD," she said.
Police arrested a Lincoln man, 36, and woman, 39, on suspicion of indecent exposure.
The man remained in custody Friday morning awaiting an initial court appearance. The woman has been released.
