32-year-old Miklos Jugovics, of Warminster, may be responsible for two incidents this month at the store on Old York Road - and more dating back to last fall.
The first incident was reported on March 21st when a female customer told police she was trying on clothes when she saw a small device under the wall.
The victim told police she tried to grab it when it was pulled away. She went on to tell police she believed she was being recorded.
Staffers at the Target store gave police a surveillance photo of a man seen in the area at the time of the incident.
Then, on Saturday, employees saw a man near the dressing rooms who matched the suspect's description.
Police were called to the store and Jugovics was taken into custody.
Investigators say Jugovics allegedly told them he was, in fact, recording women in the changing rooms using a ballpoint pen with a built-in video camera.
Jugovics would download the images to a personal computer, police say, but he claimed he never uploaded them to the Internet or distributed them.
Police believe Jugovics may be responsible for other incidents dating back to November.
Any potential victims, or anyone with information, are asked to call Detective Lisa Burton at 267-536-1108 or Detective Sergeant Greg Urban at 267-536-1095.
Jugovics was charged with Invasion of Privacy, Unlawful use of Computers and Possessing Instruments of Crime.
He has been arraigned and was released on $10,000 bail.
