She had been rushed to UCLH by ambulance after complaining of dizziness, itching, and a high temperature, having previously survived breast cancer.
While at the hospital, Laimou reportedly messaged a friend saying, 'nobody is checking up on me, nobody is coming,' before being discharged with antibiotics.
Her family claims no doctor examined her at UCLH and alleges the hospital failed in its duty of care, with plans to take legal action.
The official diagnosis given by doctors was a 'toxic effect of venom' caused by an 'animal or insect bite,' and UCLH has initiated an internal investigation into her death.
