A woman is facing jail after admitting to biting off her boyfriend's testicles during a drunken brawl. Maria Topp, 44, from Wrekenton, Gateshead, pleaded guilty to grievous bodily harm at Newcastle Crown Court. The mother-of-four bit Martin Douglas, her partner of five years, during a drunken brawl at his flat in February, reports ChronicleLive. She was granted bail to be sentenced next month and Recorder Robin Mairs warned her: "All options are open and that will include locking you up." Mr Douglas, 45, needed emergency surgery to reattach his genitals after Topp bit them off in the early-morning attack. The badly-injured victim has since recovered in hospital following the incident. Mr Douglas, who works as a DJ, called 999 himself after the alleged attack at his flat in Waterloo Street, Newcastle. Paramedics then called police and Topp was arrested. Mr Douglas, whose arm was also injured, spent several days in Newcastle's Freeman Hospital, where he received treatment. Topp cannot remember biting her partner, but can recall their fight, and the court accepted that violence had been used by both sides. Prosecutor Gavin Doig said Topp originally claimed she ripped the testicles off with her HANDS. "Her plea now is on the basis she did indeed cause that injury with her teeth," he said. Topp denied grievous bodily harm with intent but admitted the lesser charge on the basis that there was violence used on both sides.
