A police team led by Deputy Commissioner of Police H S Revanna launched the hunt for the culprit on the complaint from a woman that she has been receiving messages from a man who threatened to put her photo on the internet, if she spurned his demand for spending a day with him.
The man, who had been working as a 'pizza delivery boy', managed to collect mobile phone numbers of the women while visiting their places. Police said the man, arrested on June 16, had blackmailed at least ten women.
He had been jailed earlier for his involvement in a counterfeit currency racket, the sources added.
