Residents of estates managed by the Leathermarket Joint Management Board have been warned to beware of conmen pretending to be official workers.
The JMB says that it is aware of two recent incidents on the Lawson Estate where thieves have attempted burglaries. Residents should be very careful if anybody comes to their door asking to come in to their house.
"Before you let anybody in to your home, make sure you are happy that they need to be there," say JMB manager Andy Bates.
"Anybody working for the JMB or other official bodies, such as gas or electricity workers, will carry an identification card, even in an emergency.
"If they say they do not have their identification with them then they are probably attempting to trick you.
"If you are unsure whether somebody should be there, do not let them in. Close your front door and contact the JMB office by ringing 020 7525 1600, any time of day or night. We will confirm whether they should be there. Do not trust them to call on your behalf."
