Beware if you get anonymous phone calls or the same on the internet, giving you attractive offers or loans without risk or interest. You must not get entrapped. First verify them and then take the plunge if things are transparent. Otherwise, there is a possibility of your getting duped by fraudsters. Statistics revealed that cyber crime cases are on the rise in the state over the past few years and people should be wary if anyone offers anything over phone or internet. People should soon inform police station if they are cheated, said SSP STF Dr Sadanand Date while talking to The Pioneer on Wednesday.
