A raider sneaked his way into the home of a 90-year-old woman to steal more than £13,000 worth of jewellery,while she was taking a bath.

The pensioner, of Pelham Court, Fulham Road, Chelsea, was bathing at around 2pm last Tuesday when she heard a loud crash. Fearing one of her paintings had fallen off the wall, she put on her dressing gown and went to investigate to find the burglar crounched behind the sofa.

The intruder told her to go to her bedroom and pushed her in the chest. He then took a £4,000 diamond ring and a £2,000 eternity ring, both with white gold bands, a £7,000 pearl necklace with a diamond clasp, and two Peter Jones watches valued at £450.

The robber - who ripped the phone cord out of the wall as he left -  is black, aged 30, 6ft, with 'very long teeth'. He was wearing a baseball cap and light-coloured anorak.

Detective Constable Sam Vennart said: "This was a terrifying ordeal. Although she appears to be recovering well from the shock of the incident, she is still very upset at the loss of her belongings. Please remember to make sure all doors and windows to your property have adequate locks."
