Mumbai police’s cyber crime department on Monday urged people to not fall into the trap of frauds in the guise of “lucky draws” ahead of Diwali. These offers spike during the festive season.

Fraudsters are sending different offers with titles like ‘online shopping lucky draw contest’ as well as scratch cards and letters in the name of reputable e-commerce firms to people claiming they have won prizes ranging from Rs 1 lakh to R10 lakh, an official said.
