Joseph Clarke Jr., 29, of the 1800 block of Bridgetown Pike in Feasterville, was arrested on Thursday and charged with more than two dozen counts of attempted invasion of privacy and related counts.
According to Lower Southampton Police, the investigation began when a woman noticed a hand, holding a phone, reaching over the wall separating the booths at the Planet Fitness located on Brownsville Road.
She reported the incident to club management, who went back to the surveillance video.
According to police, the video showed Clarke following multiple women into the tanning booth section.
Investigators say Clarke was involved in 27 incidents between April 20 and April 25th.
Clarke is being held in lieu of 10% of $500,000 bail.
Police say they have only been able to identify a handful of the women who were involved, including a girl who was under 18.
They are asking anyone who tanned at Planet Fitness, and recognizes Clarke, to contact police at 215 357-7300.
