After an eight-month-long investigation, a former professor at the University of San Francisco and SF State stands accused of using a secret bathroom camera to record students from both schools as they used the facilities.

Mark Landis had taught accounting at SF State since 2006, and at USF for less than two years when a student at a November, 2013 party at Landis' home noticed a tissue box on the toilet that, he discovered, contained a camera, the Ex reports.

The student took the memory card for the camera, and later "examined the contents of the memory card and saw that there were many instances of guests being filmed in the bathroom," then turned the footage over to police.

SF District Attorney George Gascon told KTVU that at least 15 people appeared on the bathroom-cam tape, many of whom were past and current students of Landis'.

Landis was arrested on Wednesday and was charged with 15 misdemeanor counts of invasion of privacy. He is scheduled to be arraigned next Tuesday, and has been released on $100,000 bail.

SF State spokesperson Ellen Griffen told KTVU that Landis resigned from the university last Friday, and USF said that he stopped teaching for them after "allegations surfaced late last year."

A subsequent investigation into Landis' alleged bathroom photography studio has uncovered even more video, with, as Gascon put it, "many more victims," all of whom need to be identified.

Therefore, anyone who believes that they might have been caught on Landis' camera is encouraged to call the Police Department’s Special Victims Unit at (415) 553-1521 or the District Attorney’s Office at (415) 553-1751.
