A murder investigation is underway and an officer has been suspended after a man was shot dead in a police operation in north London.
The Independent Police Complaints Commission (IPCC) confirmed on Monday night that it had begun a homicide investigation.
Jermaine Baker, 28, from Tottenham, was killed by a single bullet in the Wood Green suburb on Friday morning as part of an "intelligence-led" operation.
The IPCC stressed that criminal charges may not necessarily follow the launch of its investigation.
Police said the shooting was part of an ongoing investigation by the Met's organised crime command, which has led to four men being charged with conspiracy to aid the escape of Izzet Eren, 32, and Erwin Amoyaw-Gyamfi, 29, from custody.
Eren and Amoyaw-Gyamfi were being transported to Wood Green crown court for sentencing on gun possession charges.
The four men charged in connection with the heist are: Ozcan Eren, 31; Eren Hasyer, 25; Nathan Mason, 30; and Gokay Sogucakli, 18. They will appear at Wood Green crown court on 4 January and were remanded in custody.
The Met's Deputy Assistant Commissioner Peter Terry said: "The exact circumstances that led to Mr Baker's death must be thoroughly and independently examined. That is the role of the IPCC. It is only through establishing the full facts, as quickly as possible, as to what took place that day that the best interests of justice and of all those affected can be served.
"All of our firearms officers, who are all volunteers, do a job that is difficult and often dangerous. They all fully understand, quite rightly, that they will need to account for their actions if they use lethal force.
"All of our officers involved in Friday's operation are receiving all the possible support we can provide. This is a very difficult time for everyone affected by the death of Mr Baker."
