The principal of a Romanian high school is to buy a breathalyser to test students and teachers in the morning.

Principal Ruben Filimon, of Mihai Viteazul High School, in Oradea, Bihor country, said he noticed many students, and also teachers, appeared to be "very tired" when they come to school.

He said the penalties for those who are caught off-guard will be a one day suspension and "a surprise anti hang-over lesson".
