TAMPA — A Bloomingdale High School teacher accused of hiding phones in a changing area to record students undressing was arrested again Friday after detectives found more photos and videos on devices seized during the investigation, deputies said.
Mark Ackett, 50, faces an additional 311 counts after investigators found 238 videos or images of students in various stages of undress and 72 videos and images showing female students with their breasts or buttocks exposed, according to the Hillsborough County Sheriff's Office. Another video showed an undressed adult, deputies said.
The additional charges bring the total number Ackett faces to 579.
Investigators have not released the total number of victims in the case, but an affidavit for a search warrant filed in December states there are at least 70. The students range in ages from 14 to 18, court records show.
Ackett of Plant City was first arrested on Sept. 11, the same day a 17-year-old student in his class discovered two cell phones hidden in the classroom changing area where she and her classmates disrobed to try on garments they made for class assignments.
