The charge sheet filed before Chief Metropolitan Magistrate Vidya Prakash alleged that businessman Narender Khosla was involved in intimidating politicians by sending them SMSes using the SIM card procured on the name of a gym instructor Manik Verma in 2010.
Police said that the businessman had downloaded Verma's photograph from his profile on the Internet to make a driving licence which was used as identity proof to obtain the SIM.
The charge sheet said the motive behind sending the threatening messages to politicians was to cause trouble for Verma who had an affair with a girl in whom Khosla was also interested.
The businessman has been charge sheeted under various provisions of the Indian Penal Code and under the Information Technology Act for using fake documents to get the SIM and for sending offensive messages.
Khosla's employee Rohit, who prepared the fake licence and assisted him in the plan, has also been charge sheeted.
The court, meanwhile, has directed the Investigating Officer to "pursue the matter rigorously" with the Forensic Science Laboratory and place before it the results of forensic opinion on mobile phones and computer disks used by the accused.
Besides Tharoor, SMSes were also sent to CPM leader Brinda Karat, Defence Minister A K Antony and Bajaj Group chairman Rahul Bajaj, the charge sheet said.
Khosla had allegedly also prepared Verma's fake profile on Internet portraying him as gay.
