A woman has been sentenced to eight months in prison for threatening to bomb a Beijing subway station, a prosecutor responsible for the case revealed on Monday.

The defendant surnamed Wang, in her 50s, called subway officers on Oct 30, saying that she would bomb Jianguomen subway station on Line 1, according to Li Mei, the prosecutor from Beijing Xicheng District People's Procuratorate.

The call lasted about 10 seconds and the police were quick to respond, Li said.

"Wang said that she felt annoyed after she fell down in crowds on the subway,” said the prosecutor.

After calling the police, the woman became increasingly irate and threatened to set off an explosive device, Li said.

Her behavior contravened China's laws, disturbed the peace and could have caused widespread panic, the prosecutor added.
