According to Swedish police, two con artists collected deposits from 27 would-be renters for the same Stockholm apartment.
The pair were arrested at the apartment after two people discovered that they had both paid for the same place.
The suspects face up to six years in prison if convicted of aggravated fraud.
A police investigator said that the suspects had access to the apartment in Gardet, a Stockholm district developed in the 1930s and 1940s and known for its modern architecture.
They allegedly placed ads on a Swedish Web site similar to Craigslist and other sites and showed the apartment to those who responded.
At least 27 people paid deposits of 20,000 kronor ($2,989), police said.
