The city crime branch has registered an FIR based on allegation by Rais Khan, a former aide of social activist Teesta Setalwad, that his email account was hacked.

"An FIR has been registered in connection with the alleged hacking of email account of Khan," DCP crime branch Himanshu Shukla told PTI.

The FIR was filed after Khan, in an application to city Police Commissioner last year, had alleged that his email account was hacked by Setalvad, Shukla said.

However, he clarified that Setalvad's name was not in the FIR with regard to Khan's allegation, and the matter was under investigation.

In his application to the city Police Commissioner in September last year, Khan had alleged that Setalvad, convener of Centre for Justice and Peace (CJP), had hacked his email, after he parted ways with the organisation in 2008.

After riots in 2002, Khan had worked as co-ordinator with CJP, headed by Setalvad, from February 28, 2002 to January 18, 2008.

Khan had further alleged in various courts hearing the 2002 riot cases that witnesses were tutored, cheated and made to sign false affidavits by Setalvad.
