Police are urging residents to take care of their jewellery for forthcoming Hindu festivals.
Members of the Asian and Hindu communities take part in autumn festivals, Diwali and Navrati, to celebrate the triumph of light over dark.
Police said they see an increase in robberies and burglaries largely due to more gold and jewellery being worn as the local community travel across the borough to celebrate.
Police are calling on people to stay vigilant during the religious festivals and to make sure possessions are secure.
They are asking people to cover jewellery, photograph items to assist police in recovery, use well-lit streets and avoid walking alone.
Chief Inspector John Fish, from Redbridge police, said: “The overt wearing of valuable jewellery and the periods when residents are away from their homes to attend festivals and events presents an opportunity for scurrilous criminals.
“Our aim is to make it as hard as possible for them to identify and target individuals and their homes. We will respond robustly to those responsible for committing any offences and thoroughly investigate any crimes which occur.
“Engaging and working with our public is key to this and I am confident our communities will work with us to reduce crime and identify offenders.”
