Rachel Cerfontyne, deputy chairwoman of the Independent Police Complaints Commission, has revealed that the watchdog are to review the death of Mark Duggan who was shot by a police in August 2011.
The watchdog plans to follow “a number of significant lines of inquiry” and speak to key witnesses.
Ms Cerfontyne said: “Having assessed the evidence at inquest, there are initially a number of significant lines of inquiry which we are pursuing.
“These include following up concerns about the way the police responded to intelligence and seeking to interview some key witnesses who have so far declined to speak to or be interviewed by us or whose accounts are inconsistent with other evidence.
“We expect police officers to cooperate fully with us if required, including answering questions at interview, something they have so far refused to do.
“We know that the family’s confidence in us and our investigation was damaged by mistakes made in the early stages — both in relation to inaccurate information we provided to the media, and the initial management of the incident.”
