A trainee at Taiwan's Police College faces criminal charges and possible expulsion after allegedly swapping intimate photos with a teenage girl online, a case that puts the school's vetting of future officers under scrutiny.

• A student surnamed Lai met the girl online, and their video chats turned sexual with private photos traded back and forth.
• The girl's parents found out and went to police; Kaohsiung prosecutors say he broke the law protecting children and teenagers.
• He was picked up in Taipei, where he was doing a summer internship at a police station, and released on bail while the case continues.
• The Police College said it will run its own disciplinary review, and expulsion is on the table.
• The Taipei precinct hosting him said it was kept in the dark about the case until the search warrant arrived.

Outlook: Prosecutors are still gathering evidence, and the school's disciplinary ruling will likely land before the case reaches court.
