New Delhi, Sep 18 (IANS): Six persons impersonating as Income Tax officers, who came for raiding a businessman's residence in south Delhi, were on Sunday beaten up by an angry mob before being handed over to the police for extorting Rs 20 lakh.

Police said the incident occurred around 12 noon when the accused persons barged into the businessman's house in Malviya Nagar posing as senior IT officers and asked to search the premises.
