A teacher at a university in China received an SMS from a student who threatened dire consequences if better grades were not awarded him.
The teacher from Nanjing city in Jiangsu province received the SMS message on July 17, cursing her family to death for giving a student a low grade.
Thereafter, Yang received three more text messages demanding she enhance the scores or face retaliation, the China Daily cited China Youth Daily as reporting.
The message mentioned the teacher's son and warned: ‘I will put you in pain.’
Tracking the phone number led to a student who had been given a low grade.
The teacher then reported the matter to police.
The student later sent a text message to apologise for his behaviour and claimed he acted on impulse as he felt the grade was unfair.
