A CCTV image of a woman has been released after a pensioner's purse was stolen following a bank visit. 

The woman, in her 70s, withdrew £1,500 from Lloyds Bank in High Street, Walthamstow, at around 4pm on March 17. 

She was then followed into Argos by the woman pictured and a man.

The pair approached her and offered to help her in some way, before leaving the store. 

The pensioner then realised an envelope containing the cash had been taken from inside her bag. 

Police have footage of the pair following the pensioner but it has not released. 

Anyone with information is asked to contact police on 101 quoting 4905390/15 or Crimestoppers anonymously on 0800 555 111.
