The investigation team is also trying to find out why he chose this area to stay for about three hours. The possibility is also being investigated whether he was waiting for any help or signal from any sleeper cell.
The second aspect of the investigation revolves around doctors from a university in Faridabad, whose names have emerged during the investigation. Police are investigating the number of active and inactive members associated with this suspicious network, which is likely to be linked to a sleeper cell.
According to sources, officials suspect that the Delhi blast and the recovery in Faridabad could be part of a larger terror network operating across the state borders. The agencies are also probing the source of the recovered weapons and explosives, whether they arrived separately, and who helped in their delivery.
Authorities are reportedly tracking down other members of the Telegram group used for communication to find out how long it has been active and who operates it. The investigators are also trying to find out whether Umar, Muzammil or Adil had themselves spied in Delhi or had taken the help of someone else for the work.
