The crime branch is probing foreign trips made by some leaders who were on stage at the Azad Maidan rally that preceded the violence on August 11.
Investigators are also looking into overseas calls made by these persons, and are trying to establish the source of funds for the rally, which may point to a conspiracy.
A senior crime branch official who shared this information refused to comment on the outcome of this line of investigation. “At this stage, we cannot say if any of this will eventually have any relevance to the investigation, but we are verifying all angles,” the official said.
The crime branch source said police have recorded statements of some of the 17 people who were on stage. The special investigation team (SIT) is probing if there was any conspiracy behind the attack, and the foreign trips of some of these persons may hold clues.
The conspiracy angle gained currency after police discovered that doctored images were uploaded on social networking sites from across the border, purportedly to instigate people.
The police are also investigating if it the funds for the rally came from the official organisers, or if there was any external help.
Investigators have discovered meetings to plan the rally were held post midnight. These were conducted not at the office of Raza Academy, but at a different location in the city. “We are checking why the regular office was not used,” the official said.
