This is the moment when a mother was caught on security cameras breaking a glass on the head of her son's teacher, after a dispute they had inside a cafeteria and was under the influence of alcohol.

Kelly Thomas, 38, has been ordered to pay £600 compensation to the assaulted teacher, who was left horrified when she saw herself on CCTV footage, the Telegraph reports.

According to the court, the mother was under the influence of alcohol when in a cafe in Porthcawl, England, a dispute began between them and at one point the mother poured the drink in his face and then broke the glass on his head.

According to prosecutor Jenny Yeo, the victim was taken to hospital for treatment after receiving minor facial injuries.

The teacher said that this attack has affected her life, as now she has marks on her face which the students are constantly looking at.
