Teen stabs mum, hacks off penis high on meow meow A TEENAGER stabbed his mother before cutting off his own penis after he was believed to have taken party drug mephedrone, commonly known as meow meow. The 19-year-old student hacked at his private parts with a knife after attacking his mother at their family home, it was claimed. He was discovered hanging out of a bedroom window, blood gushing from his groin after his terrified mother called emergency services to the house in Haywards Heath, West Sussex. Both he and his 46-year-old mother, neither of whom have been named, were rushed to hospital by ambulance with injuries described as life threatening after the attack on December 29, according to the Mirror. Yesterday she was described as being in a stable condition at the Royal Sussex County hospital in Brighton. Surgeons at University College London hospital are thought to have re-attached the teenager's penis, and his condition was also described as stable. He is believed to have taken mephedrone, a former so-called legal high also known as M-Cat which was outlawed in 2010, before the attack.
