Maria Topp pleaded not guilty to causing grievous bodily harm to her partner Martin Douglas

Maria Topp, 43, who has four children, pleaded not guilty to causing grievous bodily harm to her partner, Martin Douglas, 45, who needed emergency surgery to re-attach his genitals.

Mr Douglas, a DJ, called 999 in excruciating pain at around 4am and operators struggled to understand what he was saying.

The pair had been out drinking prior to the incident on the night of February 18.

Paramedics who attended his flat in Newcastle called police and Topp was arrested. Mr Douglas was forced to spend several days in hospital recovering from the alleged attack which also included injuries to his arm.

Topp, of Wrekenton, Gateshead, denies the allegations, and defence barrister Caroline Goodwin told Newcastle Crown Court her denial was “absolute”.

She added: “The defendant was on her back with the victim straddling her.”
