An enterprising thief got an “A” for ingenuity on Sunday after taking advantage of a professor’s prohibition on mobile phones.

According to police, a large number of medical students had left their phones under their moto seats during medical exams after the instructor at the Daun Penh district site said phones would not be allowed.

After the exams, 20 iPhones and Samsung mobiles came up missing.

The school security guard – charged with watching the parking lot – denies having taken the phones and police are investigating.
