Marcela Telehanicova, of Ivybridge, England, woke last week to find an army of gnomes neatly arranged in formation in her front yard, thirty rows deep.
In a story headlined "Call Gnomeland Security," The Plymouth Herald reports that the statuettes were placed there sometime between 9.30pm on June 1 and 1.30 am on June 2.
"I had a second look, thought 'What is that?'" she said. "Then I realised they were little people."
Marcela, who lives with her young son, says the figures were made of plastic and moulded into the shape of little workmen.
"I was in hysterics, I found it really funny," she said.
"It's the best, most bizarre thing that has ever happened to me.
Local police suspect that an equivalent number of gnomes may well be missing from other people's yards. "No gnomes have been reported missing," a police spokeswoman said. "The question is whether they are stolen, as opposed to being gnomeless."
