Graduate accountants were 'held to account' today when a bottle was thrown from their bus at Sa Maison.
The graduands were celebrating loudly on a private bus heading towards Valletta.
The bottle-throwing was spotted by policemen in two police cars.
One of them immediately blocked the bus and officers were seeing going on board and noting particulars.
The bus driver also sternly warned the graduands not to throw anything from the windows, and to lower the music.
The students were then allowed to proceed.
