Maria Georgina Topp, 43, appeared in court accused of carrying out the horrific attack on her boyfriend Martin Douglas, 45, in Newcastle, northern England.

Douglas had to call emergency services himself after the incident, but was in so much pain operators could not understand what he was saying. He needed emergency surgery and had to spend several days in the hospital recovering from the attack.

Paramedics who attended the scene called police when they saw the extent of his injuries and Topp was arrested and charged with causing grievous bodily harm.

A Northumbria Police spokesman said, “At around 4:00am [local time] on Friday, Feb. 18, police were called to a report of an assault. Officers arrested a 43-year-old woman on suspicion of assault. A 45-year-old man was taken to the Freeman Hospital for treatment to injuries to his arm and groin area.”
