(DAILY MAIL) — Three fifth-grade students have been expelled from their school after allegedly lacing a female teacher’s coffee and cupcake with rat poison.

She was saved when one of the students at Balderas Elementary in Fresno, California had a change of heart, knocking the cup off her desk.

The students – two boys and a girl aged 10 and 11 – have now been placed in new schools, authorities said.
