Images of two men police wish to speak to as part of their investigation into the theft of a bank card have been released.
The card, which belonged to a 90-year-old man, was stolen on or prior to November 5 2013 and the offender, or offenders, have since made a number of purchases on it in Ilford shops.
Officers believe the two men may have witnessed the theft or the transactions, or have information which can assist the investigation.
The stolen card has also been used in stores in Palmers Green and Chingford, London.
If anyone recognises the men, or they recognise themselves, they should contact Hertfordshire police on 101, giving the reference number J1/13/3526.
Alternatively, members of the public can call Crimestoppers anonymously on 0800 555 111.
A spokesman for Hertfordshire police said residents should protect themselves by never revealing their PIN to anyone, calling the police and informing the bank if they believe a cashpoint has been tampered with and by shielding PIN pads with their hands when using them.
People should also alert officers if they see anyone acting suspiciously nearby and should change their PIN at a cash machine if they believe someone has seen it.
