University of Delaware students are being offered counseling after a doctoral student allegedly hid video cameras in restrooms around the university 's Newark campus over a two-year period . Police were alerted after a hidden camera was discovered in a women 's restroom on June 27 , the university said . An investigation led to the arrest of 38-year-old Javier Mendiola-Soto , a doctoral student from Mexico . Mendiola-Soto has been charged with 21 counts of violation of privacy . His visa has been revoked , and he is in custody . Police searching Mendiola-Soto 's home found approximately 1,500 computer video files . `` The analysis concluded that the suspect hid video cameras in other restrooms both on and off campus over a more than two-year period from 2012 until his arrest this month , '' the university said in a statement . `` The scope of the recordings continues to be a focus of the investigation , and the police are attempting conclusively to identify all potential recorded locations . '' Recordings have been traced to two restrooms at the Delaware Biotechnology Institute -- where Mendiola-Soto worked -- a unisex bathroom in the building housing the education department , and women 's restrooms in a library , memorial hall and laboratory , the university said . The investigation has so far identified approximately 40 potential victims . Police are contacting victims , and the university is offering counseling to anyone who requests it in connection with the case . `` It is extremely disturbing that this crime was perpetrated against our community invading the privacy of so many women on and around this campus , '' university President Patrick Harker said . `` We have implemented several actions already , including security sweeps of all restrooms and changing rooms on all campuses , randomly timed examinations of all restrooms by custodial staff and increased police patrols throughout buildings , '' he said . The university 's head of campus and public safety , Skip Homiak , said new technology had increased the risk of such crimes . `` Invasions of privacy crimes are becoming an increasing concern on college campuses and in public areas given the ready access to small and sophisticated spying devices , '' he said . The university said the investigation was being conducted `` under strict guidelines and protocols designed to protect the privacy of any individual whose image may have been captured on video . '' The video evidence is being securely stored and will be destroyed after criminal proceedings end , it said . Police say they do n't think the images have been uploaded to the Internet or shared . People who think they may have been recorded should contact the University Police Department hotline at 302-831-4800 .
