An Elk River man is being investigated in connection with several cameras that were hidden inside dressing rooms at the Mall of America and Maplewood Mall.
Criminal charges haven't been filed against the 41-year-old suspect, but details of the investigation were revealed in a search warrant affidavit filed Tuesday in Hennepin County District Court.
Authorities contend that the man targeted stores frequented by teenage girls over several months this year. He was arrested in September and released.
The Star Tribune generally does not name suspects who have not been charged.
"On two occasions, the suspect mounted a fake shelf to the fitting room walls at waist height, and mounted the cameras under the shelves so they would not be seen unless someone purposely bent over to look under the shelves," the warrant said regarding the Mall of America cases. "These boxes were constructed so that at first glance they appeared to be only electrical junction boxes."
Officials at the Mall of America (MOA) and Maplewood Mall did not respond to messages seeking comment.
Bloomington police investigated the MOA cases, reporting that four GoPro cameras were hidden in the fitting rooms of Hollister and Forever 21 stores between March and September. They learned of a similar case at the Hollister store at the Maplewood Mall.
"[The suspect] thinks he has done this approximately 10 times in the MOA and other malls around the metro," the warrant said. "He admitted that some of the people he watched dress and undress were possibly children, but he couldn't always tell."
