Sarah Childs sued Denham Springs, its mayor and police chief, claiming she was threatened with arrest if she didn’t take down the display.
The American Civil Liberties Union of Louisiana filed the suit Thursday on Childs’ behalf. Soon after, U.S. District Judge James Brady issued a temporary restraining order barring officials from interfering with the display in the city near Baton Rouge.
Childs erected the lights last month as part of a continuing dispute with her neighbors. She says she has removed them twice after one police officer told her she could be fined and another threatened to arrest her.
