"I understand the distress that the shooting of Mark Duggan has caused to his family and in the community and that people need answers about what happened to him," an IPCC spokesman said.
"This case (Mark Duggan) was referred to the IPCC immediately and we declared it an independent investigation and sent our investigators straight to the scene in Tottenham, where they took control and remained until late Friday night, supervising the forensic examinations. An independent investigation means that all aspects are carried out by IPCC investigators.
"We are in close contact with Mark Duggan's family and supported 14 family members and friends in viewing and formally identifying Mr Duggan's body. We have been in telephone contact with close family tonight and have further meetings with them tomorrow.
"I have tonight spoken to community representatives and hope to meet with them and others as early as possible. I remain in frequent contact with David Lammy, the local MP.
"We are still gathering evidence and will release further details about our progress with the investigation as soon as we can."
