An angry woman in Shanghai has been detained for nine days after she slapped a nurse who she thought did not give her husband the right treatment.

The CCTV video, filmed on February 16, shows a woman named Zhang suddenly slapping a nurse Wang repeatedly on her face and head, and also trying to grab her hair. Other nurses can then be seen managing to stop Zhang.

According to reports, Zhang’s husband started to cough and vomit after receiving the treatment. Although Wang has explained to Zhang that her husband’s reactions were normal, Zhang was not convinced and attacked Wang when other paramedics went to treat her husband.

Zhang has been detained for nine days and also fined by police.
