Sportcheck again

Today, when BM period, we practice for our drama... suddenly, there is a pengumuman "Diminta semua pelajar turun ke dewan bakti sekarang"

Our BM teacher say that one of the teachers lost her purse... Wow... who so geng?! stole teacher's purse... when we go down, the teacher ask "kamu tau kenapa berada di sini tak?" after that, prefect call us to stand up and check our body with a pen... Someone found the purse in the toilet but no money...

Don't know who is the "person" leh... form what student?
