Police has launched a search for a person who had allegedly threatened to join dreaded terror outfit ISIS if the hanging of 1993 Mumbai serial blast convict Yakub Memon was not stopped.
The threat was posted on Facebook page, a source from the crime branch said.
This came to light a couple of days ago when a social media user informed police about the post on the popular social networking site, he added.
Crime branch has been successful in tracing the Internet Protocol address from where the comment was posted, he said, adding that the Cyber cell is probing the case.
Police declined to divulge further details of the case.
Yakub Memon, the lone 1993 Mumbai serial blasts convict, was hanged on July 30 at the Nagpur Central jail.
