No charges should be brought against the police officer who shot dead a 52-year-old man, a report has claimed.
The Independent Police Complaints Commission (IPCC) carried out a six-month investigation into the killing of Terry Nicholas.
He was shot in May when armed Metropolitan Police officers opened fire in Hanger Green, Park Royal.
"From our investigation there is no evidence to suggest officers committed any offence," the report said.
A loaded 9mm pistol was recovered from the scene and a bullet from this weapon was found lodged in the police vehicle carrying the officers.
IPCC Commissioner Deborah Glass said: "Our investigation looked into the actions of the officers firing the shots at Terry Nicholas as well as the planning, decision-making and implementation of the police operation."
Ms Glass said their full report would be published on completion of the inquest "taking into account any further evidence given".
The IPCC's report will now be sent to the West London Coroner. An inquest date has yet to be set.
